Sandpaper electrode harvests electricity from friction

Written by James Sudlow for Chemistry World.

Researchers in South Korea have developed a method to turn common sandpaper into an electrode that generates current from friction, promising a way to power portable devices with ambient mechanical energy.

Wirelessly powering small devices by harvesting energy from the environment could eliminate the need to ever recharge them. This is especially useful for embedded sensors as they will often be located in inaccessible places without a power supply, for example, on the inside of machines or the side of buildings.
