Scientists Invent a Flexible Device That Converts Wi-Fi Signals Into Electricity

Posted by in categories: energy, internet

We can probably all agree that charging cables are just the worst, and that we’d love to have fewer of them in our lives. Now, a new invention might give us just that: engineers have developed a flexible device that harvests energy from Wi-Fi signals.

And not just harvest. It can then convert it into electricity that could be used to power devices, wire-and battery-free.

The device is what is known as a rectenna — a portmanteau of ‘rectifying antenna’ — which is a type of antenna that converts electromagnetic energy into direct current (DC).
