Underwater camera opens up more possibilities for ocean exploration

Researchers have developed a sound-wave-driven battery-free wireless underwater camera that is about 100,000 times more energy-efficient than other subsea cameras, can take color photos even in dark underwater environments, and Transfer image data. The camera's autonomous camera is powered by sound waves. It converts the mechanical energy of sound waves traveling through water into electricity to power its imaging and communications equipment. Because it doesn't require a power source, the camera can run continuously for weeks before scientists process the data, enabling scientists to search for new species in remote parts of the ocean. It can also monitor ocean pollution or the health and growth of fish in aquaculture farms by taking pictures.
