Originating from a combination of neuroscience and biomedical engineering strategies, neuroprosthetics are developed as substitutes for sensory or cognitive modality damages caused by an injury or a disease. Dry electrodes are essential devices for monitoring of the biopotential such as electroencephalography (EEG) and electrocardiography (ECG). In this paper, polyaniline (PANI) coated stainless steel (SS) electrodes have been fabricated using in-situ electrochemical polymerization on the SS surface. The SEM images showed the formation of a nanoporous PANI-coating on the SS electrodes. EIS measurements on a skin model demonstrated a significantly lower contact impedance for the PANI-coated electrodes compared to bare SS electrodes. Furthermore, increasing the thickness of the nanoporous coating resulted in a higher contact impedance reduction. The comparison of the EEG measurements for the manufactured electrodes with conventional wet Ag/AgCl electrodes showed that the electrodes could successfully monitor alpha rhythms and muscle artifacts, as well. The prepared electrode can be used in various applications such as biopotential monitoring.

源于神经科学和生物医学工程策略的组合，神经假体被开发为替代由伤害或疾病引起的感觉或认知方式损害。干电极是监测生物电势的必不可少的设备，例如脑电图（EEG）和心电图（ECG）。在本文中，使用原位制备了聚苯胺（PANI）涂层的不锈钢（SS）电极在SS表面进行电化学聚合。SEM图像显示在SS电极上形成纳米多孔PANI涂层。在皮肤模型上进行的EIS测量表明，与裸露的SS电极相比，PANI涂层的电极的接触阻抗明显更低。此外，增加纳米多孔涂层的厚度导致更高的接触阻抗降低。所制造的电极与常规的湿式Ag / AgCl电极的EEG测量结果的比较表明，该电极也可以成功地监测阿尔法节律和肌肉伪影。制备的电极可用于各种应用，例如生物电势监测。
