Overview ‹ Battery-Free Wireless Underwater Camera — MIT Media Lab

Over 95% of the ocean has never been observed by humans, even though the ocean plays the most important role in the global climate system, has so many undiscovered species and regulates the global climate.

We invented the first battery free wireless underwater camera. The camera is powered by underwater sound, captures color images at very low power and transmits them wirelessly to a remote receiver. Our electronic design consumes 100,000 times less power than state-of-the-art low-power underwater imaging systems, allowing us to power it entirely based on the sound energy harvested.

This technology paves the way for massive, continuous and long-term ocean deployments with many applications including marine life discovery, underwater monitoring, climatology, maritime archaeology, geology, space exploration , aquaculture and underwater climate change monitoring.
