From the article: The air around us is thick with radio frequency signals from Wi-Fi, Bluetooth, and 5G networks. These standards are excellent for transmitting data but also represent an untapped energy source. Researchers have developed a new technology to harvest ambient or ‚waste‘ RF signals and use them to power small electronic devices.
The key innovation is a nanoscale spin-rectifier that can convert extremely low-power RF signals of less than -20 dBm into a usable direct current voltage.
