NEW YORK: U.S. space agency NASA has developed a high-tech electroactive bandage that creates an electric charge to help promote the healing process of wounds.

Electroactive material is so sensitive that a push or even blow on it can create an electric charge.

The fibres of the guaze are made of electroactive material Polyvinylidene Flouride (PVDF) which are stimulated by the heat of the body and the pressure of cell growth, thus no external power source is required.

"This technology is a device that uses electrical activity to facilitate the wound healing process while protecting the wound," NASA wrote on its blog.

The bandage also minimises infection and related complications such as illness or amputation.

NASA said this bandage could be used by military personnel wounded in the field, patients who have undergone surgery or who have suffered a serious wound and astronauts in space.
