class='main-copy'> <p>The battery-free wireless underwater camera developed by Prof. Fadel Adib and colleagues in the Signal Kinetics lab was featured as a <b>Research Highlight</b> in the October issue of <b><i>Nature Electronics</i></b>.  The paper, originally published in <i>Nature Communications</i> this September, details the world's first underwater imaging system that can operate wirelessly and relies on harvested acoustic energy without the need for batteries. </p><p>The camera’s self-sustaining nature makes it desirable for massive, continuous, and long-term ocean deployments with many applications including marine life discovery, submarine surveillance, and underwater climate change monitoring.
