We have electric cars, razors and now an electric bandage? Researchers at the University of Wisconsin have developed an electrode-dressed bandage to help the body heal itself. Electrical currents are created when the body moves.

“We use that body- generated electricity to help the wound recovery,” said Xudong Wang, PhD, Engineering Professor at the University of Wisconsin, Madison.
