MIT engineers have built a wireless, battery-free underwater camera, capable of harvesting energy by itself while consuming very little power, according to a new paper published in the journal Nature Communications. The system can take color photos of remote submerged objects—even in dark settings— and convey the data wirelessly for real-time monitoring of underwater environments, aiding the discovery of new rare species or monitoring ocean currents, pollution, or commercial and military operations.
We already have various methods of taking underwater images, but according to the authors, “Most of…
