Abstract: This demo presents a system for real-time wireless imaging of underwater environments using a fully-submerged battery-free camera. The camera powers up from harvested acoustic energy, captures images using an ultra-low-power image sensor, and communicates wirelessly using piezo-acoustic backscatter. A demo video of the battery-free camera can be found here:https://www.youtube.com/watch?v=kyVZ1ll6_qY
