心电检测用织物电极的研究进展

摘要

The quality of ECG electrode directly affects the quality of acquired signals. The popularly used silver/silver chloride wet electrode is easy to cause skin discomfort and even allergic reaction, as well as the decline of signal quality during long time detection due to the drying of conductive adhesive. The development of fabric electrodes is becoming one of the research hot-points. In this paper, the principle of ECG is introduced firstly, and then, the material, structure, evaluation and application of fabric electrodes are presented successively.%心电电极的质量直接影响采集到的信号质量,目前常用的银/氯化银传统湿电极易引起皮肤不适甚至过敏反应,长时间监测会由于导电胶干涸造成信号质量的下降.开发舒适性良好并且性能可靠的织物电极成为了国内外研究重点.文章介绍了心电检测原理,并从织物电极的材料、织物类型、评价方法和应用领域等 4 个方面对织物电极的研究进展进行了介绍.
