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。它们作为可直接从溶液中加工的分散体的可用性使得它们对于低成本和与机械柔性基底的相容性很重要的应用特别有吸引力。在这项工作中，我们证明，聚（3，4-乙撑二氧噻吩）为基础的导电聚合物薄膜，可以通过添加丙烯酸酯共聚物微粒的解决方案中的皮肤和聚酰亚胺粘合。所得膜保持高度导电，尽管掺入至多2.5%的导电聚合物。我们表明，使用这些涂层制造的粘附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。
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.
