Researchers from the National University of Singapore presented at the IEEE MEMS 2015 last January a skin-based triboelectric generator. In human language, they created a device that generates electricity by using static energy that exists abundantly in your body.

The little devil produces 90 volts of electricity when touched with a finger. Tests were run on it attached to a human forearm, fist-clenched, and tapped. The most electricity was generated with tapping, which lit up twelve commercial LED lights.

They’re currently speculating on the possibility of this new device powering body implants, but just imagine a world without sockets and chargers. Imagine your phone’s battery never dying out on you a few years from now. If your jaw just dropped, follow through with the scientific explanation on the IEEE website.
