The rectenna, developed by Nihon Dengyo Kosaku, is relatively thin, at 12mm for Wi-Fi and 30mm for digital terrestrial broadcast waves, and uses only 50µW of power to start.

According to Diginfo:

“With wireless LANs, it can generate power in the order of micro-watts at a distance of around 10cm. Recently there are computers that can operate on power in the micro-watt range, so we think that by using that people could power sensors or tag devices.”
