MIT Wireless Underwater Camera Battery Free
Unlike the Aquanut underwater transformer robot, this wireless underwater camera, developed by MIT engineers, does not require batteries. This innovative camera is 100,000 times more energy-efficient than other undersea cameras and is capable of capturing color photos, even in dark underwater environments, while being able to transmit image data wirelessly through the water.

How is this possible? The autonomous camera is powered by sound, as in it converts mechanical energy from soundwaves traveling through water into electrical energy that powers its imaging and communications equipment. Once an image is captured and data encoded the camera also uses these soundwaves to transmit data to a receiver that reconstructs the image. This means that it could theoretically run for weeks before scientists need to retrieve the device, enabling them to explore remote areas of the ocean.

One of the most exciting applications of this camera for me personally is in the context of climate monitoring. We are building climate models, but we are missing data from over 95 percent of the ocean. This technology could help us build more accurate climate models and better understand how climate change impacts the underwater world,” said Fadel Adib, associate professor in the Department of Electrical Engineering and Computer Science and director of the Signal Kinetics group in the MIT Media Lab.
