Capturing energy from the wifi and converting it into electricity: a first device made
Along the road that leads to wireless electricity, or "witricity", there is an important new travel companion: a circuit developed by researchers at Duke University capable of capturing energy from sound and the WiFi signal with an efficiency close to that of solar cells. It is a small device that uses 5 copper and glass fiber conductors connected in a circuit through 5 channels made with a metamaterial. The circuit 'captures' energy from the aforementioned sources converting it into electrical energy... Read more
