Adhesive cutaneous conducting polymer electrodes

Conducting polymers are widely used as electrode coatings in electrophysiology to lower impedance and achieve higher quality recordings more efficient stimulation. Their availability dispersions that can be processed directly from solution makes them particularly attractive for applications, where low cost compatibility with mechanically flexible substrates important. In this work, we demonstrate poly(3,4-ethylenedioxythiophene)-based conducting polymer films made adhesive skin polyimide by adding acrylic ester copolymer microparticles the solution. The resultant remained highly despite incorporating at most 2.5% polymer. We show cutaneous electrodes fabricated using these comparable performance commercial forearm electromyography.
