Power for future devices could be harvested directly from Wi-Fi signals

Computers Technology

Wireless power is often seen as the holy grail for mobile devices, allowing charging without connecting to a power source-or in some cases without having to have an internal battery at all.

Researchers have had a breakthrough in making this a reality— publishing results in Nature — showing progress in capturing energy from Wi-Fi signals and creating a thin and flexible rectenna (radio wave harvesting antenna) — just a few atoms thick.

The significant thing is that this rectenna is applied. Because it’s so thin and flexible it could be applied to a wide range of technology-smart pills, mobile devices, wearables-allowing power harvesting without bulky design.
