Wound-healing by Alternating Current November 30, 2018

Abstract Image

Scientists at University of Wisconsin have made bandages that can cut (see what I did there?) wound-healing time from two weeks to three days. By passing small alternating currents through the wound (see above) the bandage encourages the fibroblasts to line up in scaffold formation, speeding recovery. It is thought that “biochemical substances that promote tissue growth” are also encouraged by the current.

Interestingly, the current in this experiment was supplied by nanogenerators in a belt around the patients which uses breathing motions to generate the current.
