Photographs of the microcurrent dressing (MCD) and the generated electric stimulation. a. A real image of the MCD. The different color dots represent different reservoirs. The dark color represents zinc particles acting as reducing agents, and the light color represents silver nanoparticles acting as oxidizing agents. b. The distribution of electric fields generated by the MCD. In the presence of moisture, redox reactions occur, and an electric field is generated. c. An electric potential between adjacent different electrodes was recorded using a universal power meter. d. Changes in electric potentials between adjacent dissimilar electrodes
