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

粘性皮肤导电聚合物电极

导电聚合物被广泛用作电生理学中的电极涂层，以降低阻抗并实现更高质量的记录和更有效的刺激。它们作为分散体的可用性可以直接从溶液中加工，这使得它们对应用特别有吸引力，在这些应用中低成本和与机械柔性基材的兼容性很重要。在这项工作中，我们证明了通过向溶液中添加丙烯酸酯共聚物微粒，可以使基于聚（3,4-乙烯二氧噻吩）的导电聚合物薄膜粘附在皮肤和聚酰亚胺上。尽管掺入了最多 2.5% 的导电聚合物，但所得薄膜仍保持高导电性。我们表明，使用这些涂层制造的粘性皮肤电极在前臂肌电图中显示出与商业电极相当的性能。
