US 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.
• Wounds are likely to heal much more slowly and considering the survival risks and the cost of space missions, healing wounds as fast as possible is crucial.
• This technology is a device that uses electrical activity to facilitate the wound healing process while protecting the wound. 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.
• The invention is a “simple and inexpensive means of producing fibres and mats of controlled fibre diameter, porosity, and thickness,” Nasa said.
• The device can also be used by military personnel wounded in the field, patients who have undergone surgery and even those who have suffered a serious wound.
