Abstract

We propose an organic transdermal iontophoresis patch powered by layer-built biofuel cells that is divided and series-connected to apply large electrical currents to a limited area of a skin. We fabricated biofuel cells consisting of fructose dehydrogenase(FDH)-modified anode electrode and bilirubin oxidase (BOD)-modified cathode electrode, then connected them serially. Interestingly, we found that the serially-connected four cells with 0.25 cm2 electrodes could generate larger electric currents than one cell with 1 cm2 electrodes in the range of subcutaneous resistance. The feature meets the need of iontophoresis skin patch that should generate large electric currents in a limited area of skin.
