“Electric” bandages that heal wounds quicker

Researchers have known for several decades that electricity can be beneficial for skin healing. Some engineers at the University of Wisconsin–Madison developed a device that’s convenient in the form of a bandage that goes on people’s skin. It stimulates healing using electricity generated from the body’s natural motions.

The device can reduce healing times to three days compared to nearly two weeks for the normal healing process.

Why it’s hot: This device could potentially improve the quality of life for people that suffer from acute and chronic wounds.
