A new electrotherapy device is developed by a team at the University of Wisconsin-Madison. The product is a band that harvests the energy from movement through integrated nanogenerators. This energy is later transferred into electrodes in a bandage that covers a wound on the body. The electrical currents have contact with the injured tissue and contribute to healing by zapping the area.
The electrotherapy device is expected to "help heal chronic wounds." When tested on rats, the gadget was able to expedite the healing process from 12 days to just three. This is due to the fact that "the gentler current [...] encourages fibroblast skin cells to line up [...] and to produce biochemical substances that promote tissue growth."
