As the number of portable electronics devices increases, the demand for more flexible and reliable charging techniques is becoming more urgent. A wireless battery charger differs from a traditional charger in the way the power transferred to the battery. In the latter, the power is transferred through electrical wires that connect the charger terminals to the battery terminals, while in the former; the power is transferred by induction without electrical connections. With a detection algorithm that detects the battery size and chemistry, the proposed charger will be able to accommodate a wide range of applications, and will allow a more flexible and reliable option to most of today’s portable electronics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=efficiency" title="efficiency">efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetically-coupled%20resonators" title=" magnetically-coupled resonators"> magnetically-coupled resonators</a>, <a href="https://publications.waset.org/abstracts/search?q=resonance%20frequency" title=" resonance frequency"> resonance frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20power%20transfer" title=" wireless power transfer"> wireless power transfer</a> </p> <a href="https://publications.waset.org/abstracts/43549/design-of-a-universal-wireless-battery-charger" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1462</span> Optimization of a Flexible Thermoelectric Generator for Energy Harvesting from Human Skin to Power Wearable Electronics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dessalegn%20Abera%20Waktole">Dessalegn Abera Waktole</a>, <a href="https://publications.waset.org/abstracts/search?q=Boru%20Jia"> Boru Jia</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhengxing%20Zuo"> Zhengxing Zuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Wang"> Wei Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nianling%20Kuang"> Nianling Kuang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A flexible thermoelectric generator is one method for recycling waste heat. This research provides the optimum performance of a flexible thermoelectric generator with optimal geometric parameters and a detailed structural design. In this research, a numerical simulation and experiment were carried out to develop an efficient, flexible thermoelectric generator for energy harvesting from human skin. Heteromorphic electrodes and a polyimide substrate with a copper-printed circuit board were introduced into the structural design of a flexible thermoelectric generator. The heteromorphic electrode was used as a heat sink and component of a flexible thermoelectric generator to enhance the temperature difference within the thermoelectric legs. Both N-type and P-type thermoelectric legs were made of bismuth selenium telluride (Bi1.7Te3.7Se0.3) and bismuth antimony telluride (Bi0.4Sb1.6Te3). The output power of the flexible thermoelectric generator was analyzed under different heat source temperatures and heat dissipation conditions. The COMSOL Multiphysics 5.6 software was used to conduct the simulation, which was validated by experiment. It is recorded that the maximum power output of 232.064μW was obtained by considering different wind speed conditions, the ambient temperature of 20℃, and the heat source temperature of 36℃ under various load resistance conditions, which range from 0.24Ω to 0. 91Ω. According to this finding, heteromorphic electrodes have a significant impact on the performance of the device. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20thermoelectric%20generator" title="flexible thermoelectric generator">flexible thermoelectric generator</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20gradient" title=" temperature gradient"> temperature gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20heat%20recovery" title=" waste heat recovery"> waste heat recovery</a> </p> <a href="https://publications.waset.org/abstracts/170955/optimization-of-a-flexible-thermoelectric-generator-for-energy-harvesting-from-human-skin-to-power-wearable-electronics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170955.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1461</span> Biodegradable Elastic Polymers Are Used to Create Stretchable Piezoresistive Strain Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Vahdani">Mostafa Vahdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Asadnia"> Mohsen Asadnia</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuying%20Wu"> Shuying Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Huge amounts of e-waste are being produced by the rapidly expanding use of electronics; the majority of this material is either burned or dumped directly in landfills since recycling would either be impracticable or too expensive. Degradable and environmentally friendly materials are therefore seen as the answer to this urgent problem. Here, we create strain sensors that are biodegradable, robust, and incredibly flexible using thin films of sodium carboxymethyl cellulose (NaCMC), glycerol, and polyvinyl alcohol (PVA). Due to the creation of many inter- or intramolecular hydrogen bonds, the polymer blends (NaCMC/PVA/glycerol) exhibit a failure strain of up to 330% and negligible hysteresis when exposed to cyclic stretching-releasing. What's more intriguing is that the sensors can degrade completely in deionized water at a temperature of 95 °C in about 25 minutes. This project illustrates a novel method for developing wearable electronics that are environmentally beneficial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degradable" title="degradable">degradable</a>, <a href="https://publications.waset.org/abstracts/search?q=stretchable" title=" stretchable"> stretchable</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20sensors" title=" strain sensors"> strain sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20electronics." title=" wearable electronics."> wearable electronics.</a> </p> <a href="https://publications.waset.org/abstracts/168793/biodegradable-elastic-polymers-are-used-to-create-stretchable-piezoresistive-strain-sensors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168793.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1460</span> Mathematical Modeling of Switching Processes in Magnetically Controlled MEMS Switches</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sergey%20M.%20Karabanov">Sergey M.

Currently, there is a MEMS switch design with a flexible ferromagnetic electrode in the form of a fixed-terminal beam, with an electrode fastened on a straight or cranked anchor. The basic performance characteristics of magnetically controlled MEMS switches (service life, sensitivity, contact resistance, fast response) are largely determined by the flexible electrode design.

These differences can significantly affect the VIV characteristics of the flow and subsequently the VIV response of the cylindrical structures. In this work, we present how the aspect ratio of a flexible cylinder can change the vortex structures in its wake. We will discuss different vortex dynamics which can be observed in the wake of the vibrating flexible cylinder, and how they can affect the vibrational response of the cylinder. Moreover, we will study the transition of these structures versus the aspect ratio of the flexible cylinder. We will discuss how these transitions affect the in-line and transverse forces on the structure. In the end, we will provide general guidelines on the minimum acceptable aspect ratio for the offshore riser studies which may have grave implications for future numerical and experimental works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspect%20ratio" title="aspect ratio">aspect ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20cylinder" title=" flexible cylinder"> flexible cylinder</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex-shedding" title=" vortex-shedding"> vortex-shedding</a>, <a href="https://publications.waset.org/abstracts/search?q=VIV" title=" VIV"> VIV</a> </p> <a href="https://publications.waset.org/abstracts/25475/the-effects-of-the-aspect-ratio-of-a-flexible-cylinder-on-the-vortex-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25475.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">488</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1458</span> Towards Printed Green Time-Temperature Indicator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariia%20Zhuldybina">Mariia Zhuldybina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Moulay"> Ahmed Moulay</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirko%20Torres"> Mirko Torres</a>, <a href="https://publications.waset.org/abstracts/search?q=Mike%20Rozel"> Mike Rozel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ngoc-Duc%20Trinh"> Ngoc-Duc Trinh</a>, <a href="https://publications.waset.org/abstracts/search?q=Chlo%C3%A9%20Bois"> Chloé Bois</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To reduce the global waste of perishable goods, a solution for monitoring and traceability of their environmental conditions is needed. Temperature is the most controllable environmental parameter determining the kinetics of physical, chemical, and microbial spoilage in food products. To store the time-temperature information, time-temperature indicator (TTI) is a promising solution. Printed electronics (PE) has shown a great potential to produce customized electronic devices using flexible substrates and inks with different functionalities. We propose to fabricate a hybrid printed TTI using environmentally friendly materials. The real-time TTI profile can be stored and transmitted to the smartphone via Near Field Communication (NFC). To ensure environmental performance, Canadian Green Electronics NSERC Network is developing green materials for the ink formulation with different functionalities. In terms of substrate, paper-based electronics has gained the great interest for utilization in a wide area of electronic systems because of their low costs in setup and methodology, as well as their eco-friendly fabrication technologies. The main objective is to deliver a prototype of TTI using small-scale printed techniques under typical printing conditions. All sub-components of the smart labels, including a memristor, a battery, an antenna compatible with NFC protocol, and a circuit compatible with integration performed by an offsite supplier will be fully printed with flexography or flat-bed screen printing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NFC" title="NFC">NFC</a>, <a href="https://publications.waset.org/abstracts/search?q=printed%20electronics" title=" printed electronics"> printed electronics</a>, <a href="https://publications.waset.org/abstracts/search?q=time-temperature%20indicator" title=" time-temperature indicator"> time-temperature indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20electronics" title=" hybrid electronics"> hybrid electronics</a> </p> <a href="https://publications.waset.org/abstracts/142956/towards-printed-green-time-temperature-indicator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142956.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1457</span> Inkjet Printed Silver Nanowire Network as Semi-Transparent Electrode for Organic Photovoltaic Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Donia%20Fredj">Donia Fredj</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Parmentier"> Marie Parmentier</a>, <a href="https://publications.waset.org/abstracts/search?q=Florence%20Archet"> Florence Archet</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivier%20Margeat"> Olivier Margeat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadok%20Ben%20Dkhil"> Sadok Ben Dkhil</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorg%20Ackerman"> Jorg Ackerman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transparent conductive electrodes (TCEs) or transparent electrodes (TEs) are a crucial part of many electronic and optoelectronic devices such as touch panels, liquid crystal displays (LCDs), organic light-emitting diodes (OLEDs), solar cells, and transparent heaters. The indium tin oxide (ITO) electrode is the most widely utilized transparent electrode due to its excellent optoelectrical properties. However, the drawbacks of ITO, such as the high cost of this material, scarcity of indium, and the fragile nature, limit the application in large-scale flexible electronic devices. Importantly, flexibility is becoming more and more attractive since flexible electrodes have the potential to open new applications which require transparent electrodes to be flexible, cheap, and compatible with large-scale manufacturing methods. So far, several materials as alternatives to ITO have been developed, including metal nanowires, conjugated polymers, carbon nanotubes, graphene, etc., which have been extensively investigated for use as ﬂexible and low-cost electrodes. Among them, silver nanowires (AgNW) are one of the promising alternatives to ITO thanks to their excellent properties, high electrical conductivity as well as desirable light transmittance. In recent years, inkjet printing became a promising technique for large-scale printed flexible and stretchable electronics. However, inkjet printing of AgNWs still presents many challenges. In this study, a synthesis of stable AgNW that could compete with ITO was developed. This material was printed by inkjet technology directly on a flexible substrate. Additionally, we analyzed the surface microstructure, optical and electrical properties of the printed AgNW layers. Our further research focused on the study of all inkjet-printed organic modules with high efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transparent%20electrodes" title="transparent electrodes">transparent electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanowires" title=" silver nanowires"> silver nanowires</a>, <a href="https://publications.waset.org/abstracts/search?q=inkjet%20printing" title=" inkjet printing"> inkjet printing</a>, <a href="https://publications.waset.org/abstracts/search?q=formulation%20of%20stable%20inks" title=" formulation of stable inks"> formulation of stable inks</a> </p> <a href="https://publications.waset.org/abstracts/142598/inkjet-printed-silver-nanowire-network-as-semi-transparent-electrode-for-organic-photovoltaic-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142598.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1456</span> Research on the Application of Flexible and Programmable Systems in Electronic Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yang%20Xiaodong">Yang Xiaodong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article explores the application and structural characteristics of flexible and programmable systems in electronic systems, with a focus on analyzing their advantages and architectural differences in dealing with complex environments.

Basha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A lightweight High Speed Flexible Coupling (HSFC) is used to connect the Engine Gear Box (EGB) with an Accessory Gear Box (AGB) of the combat aircraft. The HSFC transmits the power at high speeds ranging from 10000 to 18000 rpm from the EGB to AGB. The HSFC is also accommodates larger misalignments resulting from thermal expansion of the aircraft engine and mounting arrangement. The HSFC has the series of metallic contoured annular thin cross-sectioned flexible plates to accommodate the misalignments. The flexible plates are accommodating the misalignment by the elastic material flexure. As the HSFC operates at higher speed, the flexural and axial resonance frequencies are to be kept away from the operating speed and proper prediction is required to prevent failure in the transmission line of a single engine fighter aircraft. To study the influence of flexible plate’s contour on the lateral critical speed (LCS) of HSFC, a mathematical model of HSFC as a elven rotor system is developed. The flexible plate being the bending member of the system, its bending stiffness which results from the contoured governs the LCS. Using transfer matrix method, Influence of various flexible plate contours on critical speed is analyzed. In the above analysis, the support bearing flexibility on critical speed prediction is also considered. Based on the study, a model is built with the optimum contour of flexible plate, for validation by experimental modal analysis. A good correlation between the theoretical prediction and model behavior is observed. From the study, it is found that the flexible plate’s contour is playing vital role in modification of system’s dynamic behavior and the present model can be extended for the development of similar type of flexible couplings for its computational simplicity and reliability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20rotor" title="flexible rotor">flexible rotor</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20speed" title=" critical speed"> critical speed</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20modal%20analysis" title=" experimental modal analysis"> experimental modal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20flexible%20coupling%20%28HSFC%29" title=" high speed flexible coupling (HSFC)"> high speed flexible coupling (HSFC)</a>, <a href="https://publications.waset.org/abstracts/search?q=misalignment" title=" misalignment "> misalignment </a> </p> <a href="https://publications.waset.org/abstracts/42547/influence-of-flexible-plates-contour-on-dynamic-behavior-of-high-speed-flexible-coupling-of-combat-aircraft" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42547.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1453</span> Study of the Effect of Rotation on the Deformation of a Flexible Blade Rotor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aref%20Maalej">Aref Maalej</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20Fakhfakh"> Marwa Fakhfakh</a>, <a href="https://publications.waset.org/abstracts/search?q=Wael%20Ben%20Amira"> Wael Ben Amira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present in this work a numerical investigation of fluid-structure interaction to study the elastic behavior of flexible rotors.

By combining the best of both performance from conventional electronic components and the flexibility from printed circuits makes it possible to manufacture HPE at high volumes using roll-to-roll printing processes. However, several challenges must be overcome in order to accurately integrate an electronic component on a printed circuit. In this presentation, we will demonstrate the integration process of electronic components from the lab scale to the industrialization. Both the printing quality and the integration technique must be studied to define the optimal conditions. To cover the parameters that influence the print quality of the printed circuit, different printing processes, flexible substrates, and conductive inks will be used to determine the optimized printing process/ink/substrate system. After the systems is selected, an electronic component of 2.5 mm2 chip size will be integrated to validate the functionality of the printed, electronic circuit. Critical information such as the conductive adhesive, the curing conditions, and the chip encapsulation will be determined. Thanks to these preliminary results, we are able to demonstrate the chip integration on a printed circuit using industrial equipment, showing the potential of industrialization, compatible using roll-to-roll printing and integrating processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flat%20bed%20screen-printing" title="flat bed screen-printing">flat bed screen-printing</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20printed%20electronics" title=" hybrid printed electronics"> hybrid printed electronics</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a>, <a href="https://publications.waset.org/abstracts/search?q=large-scale%20production" title=" large-scale production"> large-scale production</a>, <a href="https://publications.waset.org/abstracts/search?q=roll-to-roll%20printing" title=" roll-to-roll printing"> roll-to-roll printing</a>, <a href="https://publications.waset.org/abstracts/search?q=rotary%20screen%20printing" title=" rotary screen printing"> rotary screen printing</a> </p> <a href="https://publications.waset.org/abstracts/142964/integration-from-laboratory-to-industrialization-for-hybrid-printed-electronics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142964.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1451</span> Thin Film Thermoelectric Generator with Flexible Phase Change Material-Based Heatsink</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wu%20Peiqin">Wu Peiqin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flexible thermoelectric devices are light and flexible, which can be in close contact with any shape of heat source surfaces to minimize heat loss and achieve efficient energy conversion. Among the wide application fields, energy harvesting via flexible thermoelectric generators can adapt to a variety of curved heat sources (such as human body, circular tubes, and surfaces of different shapes) and can drive low-power electronic devices, exhibiting one of the most promising technologies in self-powered systems. The heat flux along the cross-section of the flexible thin-film generator is limited by the thickness, so the temperature difference decreases during the generation process, and the output power is low. At present, most of the heat flow directions of the thin film thermoelectric generator are along the thin-film plane; however, this method is not suitable for attaching to the human body surface to generate electricity. In order to make the film generator more suitable for thermoelectric generation, it is necessary to apply a flexible heatsink on the air sides with the film to maintain the temperature difference. In this paper, Bismuth telluride thermoelectric paste was deposited on polyimide flexible substrate by a screen printing method, and the flexible thermoelectric film was formed after drying. There are ten pairs of thermoelectric legs. The size of the thermoelectric leg is 20 x 2 x 0.1 mm, and adjacent thermoelectric legs are spaced 2 mm apart. A phase change material-based flexible heatsink was designed and fabricated. The flexible heatsink consists of n-octadecane, polystyrene, and expanded graphite. N-octadecane was used as the thermal storage material, polystyrene as the supporting material, and expanded graphite as the thermally conductive additive. The thickness of the flexible phase change material-based heatsink is 2mm. A thermoelectric performance testing platform was built, and its output performance was tested. The results show that the system can generate an open-circuit output voltage of 3.89 mV at a temperature difference of 10K, which is higher than the generator without a heatsink. Therefore, the flexible heatsink can increase the temperature difference between the two ends of the film and improve the output performance of the flexible film generator. This result promotes the application of the film thermoelectric generator in collecting human heat for power generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20thermoelectric%20generator" title="flexible thermoelectric generator">flexible thermoelectric generator</a>, <a href="https://publications.waset.org/abstracts/search?q=screen%20printing" title=" screen printing"> screen printing</a>, <a href="https://publications.waset.org/abstracts/search?q=PCM" title=" PCM"> PCM</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20heatsink" title=" flexible heatsink"> flexible heatsink</a> </p> <a href="https://publications.waset.org/abstracts/133649/thin-film-thermoelectric-generator-with-flexible-phase-change-material-based-heatsink" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133649.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1450</span> Modeling Dynamics and Control of Transversal Vibration of an Underactuated Flexible Plate Using Controlled Lagrangian Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmood%20Khalghollah">Mahmood Khalghollah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Tavallaeinejad"> Mohammad Tavallaeinejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Eghtesad"> Mohammad Eghtesad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The method of Controlled Lagrangian is an energy shaping control technique for under actuated Lagrangian systems. Energy shaping control design methods are appealing as they retain the underlying nonlinear dynamics and can provide stability results that hold over larger domain than can be obtained using linear design and analysis. In the present study, controlled lagrangian is employed for designing a controller in an under actuated rotating flexible plate system. In the system of rotating flexible plate, due to its nonlinear characteristics and coupled dynamics of rigid and flexible components, controller design is a known challenge. In this paper, controller objectives are considered to be vibration reduction of flexible component and position control of the tip of the plate. To achieve the goals, a method based on both kinetic and potential energy shaping is introduced. The stability of the closed-loop system is investigated and proved around its equilibrium points.

The purpose of this paper is to understand the practical issues of integration of electronics in garments; cutting patterns for mass production, maintaining the basic properties of textiles and daily maintenance of garments that hinder the wide adoption of interactive fabric technology within Fashion and leisure wear. To understand the practical hindrances an experimental and laboratory approach is taken. “Techno Meets Fashion” has been an interactive fashion project where sensor technologies have been embedded with textiles that result in set of ensembles that are light emitting garments, sound sensing garments, proximity garments, shape memory garments etc. Smart textiles, especially in the form of textile interfaces, are drastically underused in fashion and other lifestyle product design. Clothing and some other textile products must be washable, which subjects to the interactive elements to water and chemical immersion, physical stress, and extreme temperature. The current state of the art tends to be too fragile for this treatment. The process for mass producing traditional textiles becomes difficult in interactive textiles. As cutting patterns from larger rolls of cloth and sewing them together to make garments breaks and reforms electronic connections in an uncontrolled manner. Because of this, interactive fabric elements are integrated by hand into textiles produced by standard methods. The Arduino has surely made embedding electronics into textiles much easier than before; even then electronics are not integral to the daily wear garments. Soft and flexible interfaces of MEMS (micro sensors and Micro actuators) can be an option to make this possible by blending electronics within E-textiles in a way that’s seamless and still retains functions of the circuits as well as the garment. Smart clothes, which offer simultaneously a challenging design and utility value, can be only mass produced if the demands of the body are taken care of i.e. protection, anthropometry, ergonomics of human movement, thermo- physiological regulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ambient%20intelligence" title="ambient intelligence">ambient intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=proximity%20sensors" title=" proximity sensors"> proximity sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20memory%20materials" title=" shape memory materials"> shape memory materials</a>, <a href="https://publications.waset.org/abstracts/search?q=sound%20sensing%20garments" title=" sound sensing garments"> sound sensing garments</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20technology" title=" wearable technology"> wearable technology</a> </p> <a href="https://publications.waset.org/abstracts/45888/interactive-garments-flexible-technologies-for-textile-integration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45888.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">393</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1448</span> Fabrication of Wearable Antennas through Thermal Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeff%20Letcher">Jeff Letcher</a>, <a href="https://publications.waset.org/abstracts/search?q=Dennis%20Tierney"> Dennis Tierney</a>, <a href="https://publications.waset.org/abstracts/search?q=Haider%20Raad"> Haider Raad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antennas are devices for transmitting and/or receiving signals which make them a necessary component of any wireless system. In this paper, a thermal deposition technique is utilized as a method to fabricate antenna structures on substrates. Thin-film deposition is achieved by evaporating a source material (metals in our case) in a vacuum which allows vapor particles to travel directly to the target substrate which is encased with a mask that outlines the desired structure. The material then condenses back to solid state. This method is used in comparison to screen printing, chemical etching, and ink jet printing to indicate advantages and disadvantages to the method. The antenna created undergoes various testing of frequency ranges, conductivity, and a series of flexing to indicate the effectiveness of the thermal deposition technique. A single band antenna that is operated at 2.45 GHz intended for wearable and flexible applications was successfully fabricated through this method and tested. It is concluded that thermal deposition presents a feasible technique of producing such antennas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20deposition" title="thermal deposition">thermal deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20antennas" title=" wearable antennas"> wearable antennas</a>, <a href="https://publications.waset.org/abstracts/search?q=bluetooth%20technology" title=" bluetooth technology"> bluetooth technology</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20electronics" title=" flexible electronics"> flexible electronics</a> </p> <a href="https://publications.waset.org/abstracts/56810/fabrication-of-wearable-antennas-through-thermal-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56810.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">282</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1447</span> Design and Analysis of Flexible Slider Crank Mechanism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thanh-Phong%20Dao">Thanh-Phong Dao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shyh-Chour%20Huang"> Shyh-Chour Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents the optimal design and formulation of a kinematic model of a flexible slider crank mechanism.

This leads to a real-time scheduling method that can produce a reasonably good schedule quickly. The dynamic Flexible Job Shop problem is an NP-hard scheduling problem that hybrid the dynamic Job Shop problem with the Parallel Machine problem. A Flexible Job Shop contains different work centres. Each work centre contains parallel machines that can process certain operations. Many algorithms, such as genetic algorithms or simulated annealing, have been proposed to solve the static Flexible Job Shop problems. However, the time efficiency of these methods is low, and these methods are not feasible in a dynamic scheduling problem. Therefore, a dynamic rule selection scheduling system based on the reinforcement learning method is proposed in this research, in which the dynamic Flexible Job Shop problem is divided into several parallel machine problems to decrease the complexity of the dynamic Flexible Job Shop problem. Firstly, the features of jobs, machines, work centres, and flexible job shops are selected to describe the status of the dynamic Flexible Job Shop problem at each decision point in each work centre. Secondly, a framework of reinforcement learning algorithm using a double-layer deep Q-learning network is applied to select proper composite dispatching rules based on the status of each work centre. Then, based on the selected composite dispatching rule, an available operation is selected from the waiting buffer and assigned to an available machine in each work centre. Finally, the proposed algorithm will be compared with well-known dispatching rules on objectives of mean tardiness, mean flow time, mean waiting time, or mean percentage of waiting time in the real-time Flexible Job Shop problem. The result of the simulations proved that the proposed framework has reasonable performance and time efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20scheduling%20problem" title="dynamic scheduling problem">dynamic scheduling problem</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20job%20shop" title=" flexible job shop"> flexible job shop</a>, <a href="https://publications.waset.org/abstracts/search?q=dispatching%20rules" title=" dispatching rules"> dispatching rules</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20reinforcement%20learning" title=" deep reinforcement learning"> deep reinforcement learning</a> </p> <a href="https://publications.waset.org/abstracts/159322/a-framework-of-dynamic-rule-selection-method-for-dynamic-flexible-job-shop-problem-by-reinforcement-learning-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159322.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">108</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1441</span> Pavement Failures and Its Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maulik%20L.%20Sisodia">Maulik L.

Various defects in pavements have been identified since the existence of both flexible and rigid pavement. Flexible Pavement failure is defined in terms of decreasing serviceability caused by the development of cracks, ruts, potholes etc. Flexible Pavement structure can be destroyed in a single season due to water penetration. Defects in flexible pavements is a problem of multiple dimensions, phenomenal growth of vehicular traffic (in terms of no. of axle loading of commercial vehicles), the rapid expansion in the road network, non-availability of suitable technology, material, equipment, skilled labor and poor funds allocation have all added complexities to the problem of flexible pavements. In rigid pavements due to different type of destress the failure like joint spalling, faulting, shrinkage cracking, punch out, corner break etc. Application of correction in the existing surface will enhance the life of maintenance works as well as that of strengthening layer. Maintenance of a road network involves a variety of operations, i.e., identification of deficiencies and planning, programming and scheduling for actual implementation in the field and monitoring. The essential objective should be to keep the road surface and appurtenances in good condition and to extend the life of the road assets to its design life. The paper describes lessons learnt from pavement failures and problems experienced during the last few years on a number of projects in India. Broadly, the activities include identification of defects and the possible cause there off, determination of appropriate remedial measures; implement these in the field and monitoring of the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Flexible%20Pavements" title="Flexible Pavements">Flexible Pavements</a>, <a href="https://publications.waset.org/abstracts/search?q=Rigid%20Pavements" title=" Rigid Pavements"> Rigid Pavements</a>, <a href="https://publications.waset.org/abstracts/search?q=Defects" title=" Defects"> Defects</a>, <a href="https://publications.waset.org/abstracts/search?q=Maintenance" title=" Maintenance"> Maintenance</a> </p> <a href="https://publications.waset.org/abstracts/120797/pavement-failures-and-its-maintenance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120797.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">172</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1440</span> Flexible Ureterorenoscopy as a New Possibility of Treating Nephrolithiasis in Children – Preliminary Reports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Hali%C5%84ski">Adam Haliński</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrzej%20Hali%C5%84ski"> Andrzej Haliński</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Flexible ureterorenoscopy is a surgery technique used for the treatment of the upper urinary tract. It is very often used in adult patients; however, due to the advancing miniaturization of the equipment as well as its precision, this technique has also become possible in the treatment process in children. Material and method: We would like to present 26 cases of flexible ureterorenoscopy carried out in children with nephrolithiasis of the upper urinary tract aged 6 to 17 years. The average age was 9.5 years and the children were treated in our department from June 2013 to January 2015. The first surgery in Poland took place in our Department on 06.06.2013. Because of nephrolithiasis all the children had been subjected earlier to ESWL treatment, which was unsuccessful. Results: 14 children had deposits in the lower calyx, 9 children had deposits in the middle and lower calyx and in 3 children a stone was located in the initial ureter. An efficiency of 88 % was achieved. Conclusions: Flexible ureterorenoscopy is effective and minimally invasive tool both for the diagnosis and treatment of upper urinary tract. We believe that the advancing miniaturization of the equipment and gaining experience will enable carrying out of this procedure in smaller children with high efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20ureterorenoscopy" title="flexible ureterorenoscopy">flexible ureterorenoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=urolithisis" title=" urolithisis"> urolithisis</a>, <a href="https://publications.waset.org/abstracts/search?q=endourology" title=" endourology"> endourology</a>, <a href="https://publications.waset.org/abstracts/search?q=nephrolithiasis" title=" nephrolithiasis"> nephrolithiasis</a> </p> <a href="https://publications.waset.org/abstracts/27396/flexible-ureterorenoscopy-as-a-new-possibility-of-treating-nephrolithiasis-in-children-preliminary-reports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27396.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1439</span> A Parametric Study of the Effect of Size, Position, and Number of Flexible Membranes Attached to a Circular Cylinder on the Fluid Flow Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabaouia.Maktouf">Nabaouia.Maktouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ben%20Moussa"> Ali Ben Moussa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sa%C3%AFd%20Turki"> Saïd Turki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the effect of an attached flexible membrane on the control of fluid around a circular cylinder. A parametric study has been investigated for different positions, sizes, modes as well as frequencies of oscillation of the flexible membrane. The numerical investigation was conducted for a Reynolds number equal to 150 using the commercial code Fluent 16.0 and parallel calculation into 4 processors. The motion of the flexible membrane was managed by the dynamic mesh and compiled into Fluent as a user-defined function. The first part of this paper discusses the effect of changing the position of a flexible membrane sized 8° as an angle of aperture on the aerodynamic coefficients. Results show that the flexible membrane placed at 110° from the stagnation point presents more non-linearity on the behavior of the drag coefficient compared to the drag behavior when placed at 180°, relative to the stagnation point. The effect of the size of the flexible surface was studied for the corresponding angles of aperture: 32° and 42°, respectively. The effect of modes (modes 1, 2, and 3) of vibrations has been investigated at a constant frequency of vibration f=2Hz for angles 32° and 42°. All the calculations have been done with a constant amplitude A =0.001m. A non-linearity of the drag coefficient was clearly observed for all the sizes, modes as well as frequencies of excitation. The Fast Fourier transformation shows the appearance of the natural shedding frequency and the multiples of the frequency of excitation. An increase in the modes of oscillation leads to a more linear behavior of the drag coefficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluid%20flow%20control" title="fluid flow control">fluid flow control</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20mesh" title=" dynamic mesh"> dynamic mesh</a>, <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20forces" title=" aerodynamic forces"> aerodynamic forces</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20membrane" title=" flexible membrane"> flexible membrane</a> </p> <a href="https://publications.waset.org/abstracts/164010/a-parametric-study-of-the-effect-of-size-position-and-number-of-flexible-membranes-attached-to-a-circular-cylinder-on-the-fluid-flow-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164010.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1438</span> Rethinking the Concept of Classroom Management during COVID-19 Times: An EFL Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadjer%20Chellia">Hadjer Chellia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the light of the recent global pandemic, different issues in educational research seem to invite careful considerations.

The main emerging themes revealed that EFL teachers have different pedagogical practices in relation to classroom management during the global crisis than those of normal times. In relation to flexible education theory, the teachers’ experiences suggest flexible classroom management during Covid-19; flexibility in the teaching methods, approach and design, flexibility in time, flexibility in space and pace (speed), flexibility in assessment modes and flexibility in coping with students’ well-being. The flexibility awareness helps them to develop readiness towards the future, mainly in terms of maintaining an appropriate pedagogy to face the future crisis. In terms of theoretical concepts, working on classroom management under unusual circumstances in relation to flexible education helped come out with the concept of flexible classroom management (FCM) and virtual classroom management (VCM). It is then important for educators and researchers to rethink different pedagogical concepts and mind a careful application in the case of unusual times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title="Covid-19">Covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=EFL%20educators" title=" EFL educators"> EFL educators</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20classroom%20management" title=" flexible classroom management"> flexible classroom management</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20education" title=" flexible education"> flexible education</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20classroom%20management" title=" virtual classroom management"> virtual classroom management</a> </p> <a href="https://publications.waset.org/abstracts/144965/rethinking-the-concept-of-classroom-management-during-covid-19-times-an-efl-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144965.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1437</span> Design of Optimal Proportional Integral Derivative Attitude Controller for an Uncoupled Flexible Satellite Using Particle Swarm Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martha%20C.%20Orazulume">Martha C.

Therefore, the system must be able to adjust to balance the effect of these appendages in order to point accurately and satisfactorily which is one of the most important problems in satellite design. Proportional Integral Derivative (PID) Controller is simple to design and computationally efficient to implement which is used to stabilize the effect of these flexible appendages. However, manual turning of the PID is time consuming, waste energy and money. Particle Swarm Optimization (PSO) is used to tune the parameters of PID Controller. Simulation results obtained show that PSO tuned PID Controller is able to re-orient the spacecraft attitude as well as dampen the effect of mechanical resonance and yields better performance when compared with manually tuned PID Controller. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Attitude%20Control" title="Attitude
