Towards Battery-Free HD Video Streaming

University of Washington researchers have developed the first analog video backscatter system for high-definition video streaming from low-power or battery-free devices. The new system burns as low as 250uW for HD video streaming, which is 1,000x - 10,000x less power than existing approaches, by eliminating the power-hungry components of a typical camera—enabling battery-free HD streaming from devices such as lightweight wearables or wireless security cameras.
