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.

Wouldn't the power consumed be greater than the power WiFi devices are legally permitted to transmit?

Awesome work, bro!I wonder what the frame-rate is.

This is pretty amazing! Even 10fps is sufficient for lots of applications, especially the ones in home automation and security. Well done folks!

Currently, our HD prototype can stream up to 10 frames per second. But we did emulations for power consumption, up to 60 fps.
