Hacker News with Generative AI: Energy Harvesting

New battery-free technology can power devices using ambient RF signals (nus.edu.sg)
Ubiquitous wireless technologies like Wi-Fi, Bluetooth, and 5G rely on radio frequency (RF) signals to send and receive data. A new prototype of an energy harvesting module – developed by a team led by scientists from the National University of Singapore (NUS) – can now convert ambient or ‘waste’ RF signals into direct current (DC) voltage. This can be used to power small electronic devices without the use of batteries.
