Summary:
- Researchers have developed a new technique to harvest energy from radio frequency (RF) signals, which could lead to more efficient and sustainable power sources for electronic devices.
- The method involves using a special antenna and circuitry to capture and convert the energy from ambient RF signals, such as those emitted by Wi-Fi routers, cellular towers, and other wireless devices.
- This technology could be used to power a wide range of low-power devices, such as sensors, wearables, and internet-of-things (IoT) devices, without the need for batteries or other traditional power sources.
