Self-powered electric bandages could speed up healing

Engadget ----------- Scientists have known for a long time that electricity can speed up healing for skin wounds, but the necessary power has usually tied patients to electrotherapy machines. In the future, though, it might not be much more complicated than treating a wound the old-fashioned way. Researchers in the US and China recently developed self-powered electric bandages that promise to be as easy to wear as ordinary dressings. The dressings include tiny electrodes powered by nanogenerators wrapped around your torso. All you have to do is breathe -- the movement of your ribcage activates the nanogenerators, sending low-intensity pulses to the wound area.
