IDG Contributor Network: Wi-Fi chip cannibalizes ambient Wi-Fi signals for power
Harvesting electromagnetic energy from thin air to develop self-sustaining Internet of Things (IoT) communications may become reality thanks to a new technology called HitchHike. The goal is to reduce the need for continual maintenance of the expected billions of IoT installations.
Researchers say they’re close to the finish line. Worst case scenario, they say they’ll be able to get Wi-Fi chips to run for 10 years on the same, small battery.
“HitchHike is the first self-sufficient Wi-Fi system that enables data transmission using just micro-watts of energy, almost zero,” claims Pengyu Zhang, a Stanford researcher, in a recent press release from the school.
