Electric Patch Hastens Bone Healing

Self-powered biodegradable patch zaps broken bones to heal them
University of Wisconsin-Madison engineers have developed an electrical patch called a fracture electrostimulation device for speeding the healing of broken bones. “The base of the device consists of an FDA-approved biocompatible polymer, on top of which is a thin-film triboelectric nanogenerator that’s hooked up to two electrodes. That nanogenerator converts mechanical energy produced by body movements into an electrical current, much in the same way that rubbing your sock feet against the carpet produces a static charge. The electrodes deliver the current to the bone.” MORE
