近几年可穿戴设备逐渐兴起并日益发展,本文针对传统氯化银(Ag/AgCl)电极在长期心电图(ECG)信号监测和采集过程中出现的皮肤过敏及电极阻抗发生变化等问题,就用于心电信号采集的新型传感器技术——织物电极技术展开了较详细的讨论。首先介绍了织物电极的概念及优点,对其常用的衬底材料和导电材料进行了讨论和评估,并从纺织结构方面进行了优缺点分析,随后提出了织物电极技术的评价体系。最后,本文分析了当前织物电极在市场发展中的制约因素,并对其发展前景和方向进行了展望。

In recent years, wearable devices grew up gradually and developed increasingly. Aiming at the problems of skin sensibility and the change of electrode impedance of Ag/AgCl electrode in the process of long-term electrocardiogram (ECG) signal monitoring and acquisition, this paper discussed in detail a new sensor technology–fabric electrode, which is used for ECG signal acquisition. First, the concept and advantages of fabric electrode were introduced, and then the common substrate materials and conductive materials for fabric electrode were discussed and evaluated. Next, we analyzed the advantages and disadvantages from the aspect of textile structure, putting forward the evaluation system of fabric electrode. Finally, the deficiencies of fabric electrode were analyzed, and the development prospects and directions were prospected.
