Researchers at NASA have developed a new substance that generates minute amounts of electricity, for use in a bandage that takes advantage of an electrically-based healing process. This new substance, a polymer called polyvinylidene fluoride (PVDF), produces a mild electrical current when pressure or heat, such as body heat, is applied to it.

“This method utilizes generated low level electrical stimulation to promote the wound healing process while simultaneously protecting it from infection,” according to NASA.
