No-Battery HD Video Streaming Does It with Backscatter

The result is that video streaming at 720p and 10 fps uses as low as 250 μW (microwatts) and can be backscattered up to sixteen feet. They also simulated an ASIC which achieved 720p and 1080p at 60 fps using 321 μW and 806 μW respectively. See the video below for an animated explanation and a demonstration. The resulting video is quite impressive for passive power only. – Steven Dufresne, Hackaday
