For one 5-year-old, the problem was simple: She liked to have her tummy rubbed as she fell asleep. But her mom, exhausted from working two jobs, often fell asleep herself while putting her daughter to bed. “So [the girl] invented a teddy bear that would rub her belly for her,” explains <a href="https://www.linkedin.com/in/stephaniecouch/" target="_blank">Stephanie Couch</a>, executive director of the <a href="https://lemelson.mit.edu/" target="_blank">Lemelson MIT Program</a>. Its mission is to nurture the next generation of inventors and entrepreneurs. </p><p> Anyone can learn to be an inventor, Couch says, given the right resources and encouragement. “Invention doesn’t come from some innate genius, it’s not something that only really special people get to do,” she says. Her program creates invention-themed curricula for U.S. classrooms, ranging from kindergarten to community college. </p><div class="ieee-sidebar-small"><p><a href="https://wikimediadc.org/wiki/Peter_Meyer" rel="noopener noreferrer" target="_blank"></a>This article is part of our special report, “<a href="https://spectrum.ieee.org/special-reports/reinventing-invention/" target="_blank">Reinventing Invention: Stories from Innovation’s Edge</a>.” </p></div><p> We’re biased, but we hope that little girl grows up to be an engineer. By the time she comes of age, the act of invention may be something entirely new—reflecting the adoption of novel tools and the guiding forces of new social structures. Engineers, with their restless curiosity and determination to optimize the world around them, are continuously in the process of reinventing invention. </p><p> In this special issue, we bring you stories of people who are in the thick of that reinvention today. <em><em><a href="https://spectrum.ieee.org/">IEEE Spectrum</a></em></em> is marking 60 years of publication this year, and we’re celebrating by highlighting both the creative act and the grindingly hard engineering work required to turn an idea into something world changing. In these pages, we take you behind the scenes of some awe-inspiring projects to reveal how technology is being made—and remade—in our time. </p><p><div class="rblad-ieee_in_content"></div></p><h2>Inventors Are Everywhere</h2><p> Invention has long been a democratic process. The economist <a href="https://www.bowdoin.edu/profiles/faculty/bkhan/" target="_blank">B. Zorina Khan</a> of Bowdoin College has noted that the U.S. Patent and Trademark Office has always endeavored to allow essentially anyone to try their hand at invention. From the beginning, the patent examiners didn’t care who the applicants were—anyone with a novel and useful idea who could pay the filing fee was officially an inventor. </p><p> This ethos continues today. It’s still possible for an individual to launch a tech startup from a garage or go on “Shark Tank” to score investors. The Swedish inventor <a href="https://spectrum.ieee.org/simone-giertz" target="_blank">Simone Giertz</a>, for example, made a name for herself with YouTube videos showing off her hilariously bizarre contraptions, like an alarm clock with an arm that slapped her awake. The MIT innovation scholar <a href="https://mitsloan.mit.edu/faculty/directory/eric-arthur-von-hippel" target="_blank">Eric von Hippel</a> has spotlighted today’s vital ecosystem of “user innovation,” in which inventors such as Giertz are motivated by their own needs and desires rather than ambitions of mass manufacturing. </p><p> But that route to invention gets you only so far, and the limits of what an individual can achieve have become starker over time. To tackle some of the biggest problems facing humanity today, inventors need a deep-pocketed government sponsor or corporate largess to muster the equipment and collective human brainpower required. </p><p> When we think about the challenges of scaling up, it’s helpful to remember Alexander Graham Bell and his collaborator Thomas Watson. “They invent this cool thing that allows them to talk between two rooms—so it’s a neat invention, but it’s basically a gadget,” says <a href="https://invention.si.edu/eric-hintz" target="_blank">Eric Hintz</a>, a historian of invention at the Smithsonian Institution. “To go from that to a transcontinental long-distance telephone system, they needed a lot more innovation on top of the original invention.” To scale their invention, Hintz says, Bell and his colleagues built the infrastructure that eventually evolved into Bell Labs, which became the standard-bearer for corporate R&D. </p><p> In this issue, we see engineers grappling with challenges of scale in modern problems. Consider the semiconductor technology supported by the U.S. CHIPS and Science Act, a policy initiative aimed at bolstering domestic chip production. Beyond funding manufacturing, it also provides US $11 billion for R&D, including three national centers where companies can test and pilot new technologies. As one startup tells the tale, this infrastructure will drastically speed up the <a href="https://spectrum.ieee.org/power-electronics" target="_blank">lab-to-fab process</a>. </p><p> And then there are <a href="https://spectrum.ieee.org/optical-atomic-clocks" target="_blank">atomic clocks</a>, the epitome of precision timekeeping. When researchers decided to build a commercial version, they had to shift their perspective, taking a sprawling laboratory setup and reimagining it as a portable unit fit for mass production and the rigors of the real world. They had to stop optimizing for precision and instead choose the most robust laser, and the atom that would go along with it. </p><p><div class="rblad-ieee_in_content"></div></p><p> These technology efforts benefit from infrastructure, brainpower, and cutting-edge new tools. One tool that may become ubiquitous across industries is artificial intelligence—and it’s a tool that could further expand access to the invention arena. </p><p> What if you had a team of indefatigable assistants at your disposal, ready to scour the world’s technical literature for material that could spark an idea, or to iterate on a concept 100 times before breakfast? That’s the promise of today’s <a href="https://spectrum.ieee.org/tag/generative-ai">generative AI</a>. The Swiss company Iprova is exploring whether its AI tools can <a href="https://spectrum.ieee.org/ai-inventions" target="_blank">automate “eureka” moments</a> for its clients, corporations that are looking to beat their competitors to the next big idea. The serial entrepreneur <a href="https://spectrum.ieee.org/steve-blank" target="_blank">Steve Blank</a> similarly advises young startup founders to embrace AI’s potential to accelerate product development; he even imagines testing product ideas on digital twins of customers. Although it’s still early days, generative AI offers inventors tools that have never been available before. </p><h2>Measuring an Invention’s Impact</h2><p> If AI accelerates the discovery process, and many more patentable ideas come to light as a result, then what? As it is, more than a million patents are granted every year, and we struggle to identify the ones that will make a lasting impact. <a href="https://som.yale.edu/faculty-research/faculty-directory/bryan-t-kelly" target="_blank">Bryan Kelly</a>, an economist at the Yale School of Management, and his collaborators made an attempt to <a href="https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3279254" target="_blank">quantify the impact of patents</a> by doing a technology-assisted deep dive into U.S. patent records dating back to 1840. Using natural language processing, they identified patents that introduced novel phrasing that was then repeated in subsequent patents—an indicator of radical breakthroughs. For example, Elias Howe Jr.’s <a href="https://www.si.edu/object/1846-elias-howe-jrs-sewing-machine-patent-model%3Anmah_630930" target="_blank">1846 patent for a sewing machine</a> wasn’t closely related to anything that came before but quickly became the basis of future sewing-machine patents. </p><p> Another foundational patent was the one awarded to an English bricklayer in 1824 for the invention of Portland cement, which is still the key ingredient in most of the world’s concrete. As Ted C. Fishman describes in his fascinating inquiry into the <a href="https://spectrum.ieee.org/green-concrete" target="_blank">state of concrete today</a>, this seemingly stable industry is in upheaval because of its heavy carbon emissions. The AI boom is fueling a construction boom in data centers, and all those buildings require billions of tons of concrete. Fishman takes readers into labs and startups where researchers are experimenting with climate-friendly formulations of cement and concrete. Who knows which of those experiments will result in a patent that echoes down the ages? </p><p> Some engineers start their invention process by thinking about the impact they want to make on the world. The eminent Indian technologist <a href="https://spectrum.ieee.org/gandhi-engineering" target="_blank">Raghunath Anant Mashelkar</a>, who has popularized the idea of “Gandhian engineering”, advises inventors to work backward from “what we want to achieve for the betterment of humanity,” and to create problem-solving technologies that are affordable, durable, and not only for the elite. </p><p> Durability matters: Invention isn’t just about creating something brand new. It’s also about coming up with clever ways to keep an existing thing going. Such is the case with the <a href="https://spectrum.ieee.org/hubble-space-telescope-re-invention" target="_blank">Hubble Space Telescope</a>. Originally designed to last 15 years, it’s been in orbit for twice that long and has actually gotten better with age, because engineers designed the satellite to be fixable and upgradable in space. </p><p> For all the invention activity around the globe—the World Intellectual Property Organization says that <a href="https://www.wipo.int/en/ipfactsandfigures/patents" target="_blank">3.5 million</a> applications for patents were filed in 2022—it may be harder to invent something useful than it used to be. Not because “everything that can be invented has been invented,” as in the apocryphal quote attributed to the unfortunate head of the U.S. patent office in 1889. Rather, because so much education and experience are required before an inventor can even understand all the dimensions of the door they’re trying to crack open, much less come up with a strategy for doing so. <a href="https://www.kellogg.northwestern.edu/faculty/directory/jones_benjamin_f.aspx" target="_blank">Ben Jones</a>, an economist at Northwestern’s Kellogg School of Management, has shown that the average <a href="https://www.kellogg.northwestern.edu/faculty/jones-ben/htm/ageandgreatinvention.pdf" target="_blank">age of great technological innovators</a> rose by about six years over the course of the 20th century. “Great innovation is less and less the provenance of the young,” Jones concluded. </p><p> Consider designing something as complex as a nuclear fusion reactor, as Tom Clynes describes in “<a href="https://spectrum.ieee.org/the-off-the-shelf-stellarator" target="_blank">An Off-the-Shelf Stellarator</a>.” Fusion researchers have spent decades trying to crack the code of commercially viable fusion—it’s more akin to a calling than a career. If they succeed, they will unlock essentially limitless clean energy with no greenhouse gas emissions or meltdown danger. That’s the dream that the physicists in a lab in Princeton, N.J., are chasing. But before they even started, they first had to gain an intimate understanding of all the <em><em>wrong</em></em> ways to build a fusion reactor. Once the team was ready to proceed, what they created was an experimental reactor that accelerates the design-build-test cycle. With new AI tools and unprecedented computational power, they’re now searching for the best ways to create the magnetic fields that will confine the plasma within the reactor. Already, two startups have spun out of the Princeton lab, both seeking a path to commercial fusion. </p><p> The stellarator story and many other articles in this issue showcase how one innovation leads to the next, and how one invention can enable many more. The legendary Dean Kamen, best known for mechanical devices like the <a href="https://robotsguide.com/robots/segway" target="_blank">Segway</a> and the prosthetic “Luke” arm, is now trying to push forward the squishy world of biological manufacturing. In an interview, <a href="https://spectrum.ieee.org/dean-kamen" target="_blank">Kamen</a> explains how his nonprofit is working on the infrastructure—bioreactors, sensors, and controls—that will enable companies to explore the possibilities of growing replacement organs. You could say that he’s inventing the launchpad so others can invent the rockets. </p><p> Sometimes everyone in a research field knows where the breakthrough is needed, but that doesn’t make it any easier to achieve. Case in point: <a href="https://spectrum.ieee.org/ai-robots" target="_blank">the quest for a household humanoid robot</a> that can perform domestic chores, switching effortlessly from frying an egg to folding laundry. Roboticists need better learning software that will enable their bots to navigate the uncertainties of the real world, and they also need cheaper and lighter actuators. Major advances in these two areas would unleash a torrent of creativity and may finally bring robot butlers into our homes. </p><p> And maybe the future roboticists who make those breakthroughs will have cause to thank <a href="https://www.bc.edu/bc-web/schools/lynch-school/faculty-research/faculty-directory/marina-bers.html" target="_blank">Marina Umaschi Bers</a>, a <a href="https://spectrum.ieee.org/scratchjr" target="_blank">technologist at Boston College</a> who cocreated the <a href="https://www.scratchjr.org/" target="_blank">ScratchJr</a> programming language and the <a href="https://kinderlabrobotics.com/" target="_blank">KIBO robotics kit</a> to teach kids the basics of <a href="https://spectrum.ieee.org/tag/coding">coding</a> and <a href="https://spectrum.ieee.org/topic/robotics/">robotics</a> in entertaining ways. She sees engineering as a playground, a place for children to explore and create, to be goofy or grandiose. If today’s kindergartners learn to think of themselves as inventors, who knows what they’ll create tomorrow? </p><div class="around-the-web"><div class="from-your-site__headline">From Your Site Articles</div><ul class="around-the-web__list"><li class="from-your-site__item"><a href="https://spectrum.ieee.org/manu-prakash" class="from-your-site__link" target="_blank" rel="noopener noreferrer">For this Stanford Engineer, Frugal Invention Is a Calling ›</a></li><li class="from-your-site__item"><a href="https://spectrum.ieee.org/simone-giertz" class="from-your-site__link" target="_blank" rel="noopener noreferrer">Why Simone Giertz, the Queen of Useless Robots, Got Serious ›</a></li><li class="from-your-site__item"><a href="https://spectrum.ieee.org/ai-inventions" class="from-your-site__link" target="_blank" rel="noopener noreferrer">This AI-Powered Invention Machine Automates Eureka Moments ›</a></li></ul></div></div></div><span class="" data-elid="2669502034" data-post-url="https://spectrum.ieee.org/inventions" data-authors="Eliza Strickland, Peter B.
