Abstract
A wearable medical bandage is provided having an energy harvesting generator that harvests mechanical energy from the user's natural body and muscle motions to produce electrical energy. The electrical energy induces an electric potential across the wound opening producing accelerated skin wound recovery under the voltage fluctuations produced by the power generator.
Claims19
A bandage for wounds on skin comprising:
- a flexible substrate adapted for retention on the skin at a site of the wound, the substrate having a first surface facing the wound;
- an electrical generator supported by the substrate to convert mechanical energy harvested from movements of the skin into an electrical potential;
- and
- a first and second electrode supported by the substrate in opposition along a plane of the skin and adapted to be positioned over the wound and electrically communicating with the electrical generator for receiving the electrical potential from the electrical generator and applying the electrical potential across the wound
- wherein the electrical generator comprises a first and second dielectric material brought into contact with the movements of the skin to elicit an electric potential.
