多通道同心环电极采用模版印刷在可伸缩弹性体上，以改善与皮肤的粘附性，并最大限度地减少运动伪影，用于脑电、肌电和心电图的电生理记录。这些带有聚(3，4-乙二氧基噻吩基)聚苯乙烯磺酸盐界面层的干式电极被优化，以显示出比商业凝胶圆盘电极更低的噪声水平。同心环的几何结构使拉普拉斯滤波能够以由环距离确定的空间分辨率精确地定位生物电位源。这项工作展示了一种新的制造方法，以集成和创建提高高质量电生理监测设备的空间分辨率的设计。
The multichannel concentric-ring electrodes are stencil printed on stretchable elastomers modified to improve adhesion to skin and minimize motion artifacts for electrophysiological recordings of electroencephalography, electromyography, and electrocardiography. These dry electrodes with a poly(3,4-ethylenedioxythiophene) polystyrene sulfonate interface layer are optimized to show lower noise level than that of commercial gel disc electrodes. The concentric ring geometry enables Laplacian filtering to pinpoint the bioelectric potential source with spatial resolution determined by the ring distance. This work shows a new fabrication approach to integrate and create designs that enhance spatial resolution for high-quality electrophysiology monitoring devices.
