What if you could charge your phone wirelessly… just by being on Wi-Fi AND without a battery?

Researchers at MIT – with other scientists – have made a next gen jump by creating a flexible antenna that can charge a mobile device by converting wi-fi energy to electricity. A newly designed rectenna uses Wi-Fi to create an AC current. This is another huge jump towards battery free, continually charged electronics. It isn’t truly free energy, but it’s the closest we’ve gotten.

Other exciting possibilities according to Zhang and others include powering devices for medical reasons. These kinds of devices may also transform more household objects into affordable parts of the “internet of all things”. As the paper states, “This work provides a universal energy-harvesting building block that can be integrated with various flexible electronic systems.”

I look forward to my folding iPhone X7 that doesn’t have a battery.

THE Kurt Broz is not just a personality for Nerdbot, but he's also the editor-in-chief and a real live scientist! Born on the snowy shores of Lake Erie in good ol' Cleveland, Ohio, Kurt Broz has been there and back again, now residing in sunny Southern California. You can find THE Kurt Broz in cosplay, buying comics, hiking, and even writing for Nerdbot and WLFK Productions. He may be a child of the 80's but he is certainly a man of the world.
