Samsung's new TV remote can harvest radio waves for power. What else can we power around the house by slurping up ambient Wi-Fi power?

Researchers report that lab tests of a new metasurface-based antenna that can harvest 100 microwatts of power, enough to power simple devices, from low power radio waves. This represents an ...

In Optical Materials Express, researchers report that lab tests of a new metasurface-based antenna that can harvest 100 microwatts of power, enough to power simple devices, from low power radio ...

I address this challenge by presenting a novel implementation of passive radar that leverages ambient radio noise sources (instead of transmitting a powerful radio signal) as a low-resource approach ...
