ambient RF energy harvesting

Ambient RF energy harvesting involves capturing radio frequency signals emitted by everyday sources like Wi-Fi, cell towers, and broadcast stations. These signals carry tiny amounts of energy, and specialized devices can convert this energy into usable electrical power. This enables small electronics, such as sensors or wearable devices, to operate without replacing batteries or direct power sources, by harnessing the surrounding electromagnetic environment. It’s a sustainable, low-power method to power devices passively, leveraging existing RF emissions in the environment.
