Abstract
In one example, the present invention is directed to a wound-healing patch including a flexible substrate, at least one wound electrode, at least one guard electrode and at least one return electrode. The guard electrode is positioned between the wound and return electrodes in the electrical path of current traveling between the return and wound electrodes on the surface of the skin, sinking the surface current and force the wound current to travel deeper into the tissue. In the invention, the wound electrode(s) is positioned on a portion of the flexible substrate designed to be placed over wounded tissue and the return electrode is positioned on a portion of the substrate substantially surrounding the wound and guard electrodes and is designed to be placed over healthy tissue.
