The device could help scientists explore unknown regions of the ocean, track pollution, or monitor the effects of climate change.

MIT researchers develop a battery-free, wireless underwater camera that is about 100,000 times more energy-efficient than other undersea cameras. The device takes color photos, even in dark underwater environments, and transmits image data wirelessly through the water.
