It works by tapping into a persons natural heatemploying thermoelectric generators to convert the bodys internal temperature into electricity.
The rig is part of a growing number of new battery technologies that could jump-start personal technology.
A series of thin thermoelectric chips are then stuck into the base, connecting them with liquid metal wires.

“These new batteries would be highly safe, non-flammable, and potentially cheaper.
“To charge quickly, the batteries need to be able to get really hot.
We can charge quickly because we can operate at high temperatures.”
