织物结构对纺织结构电极阻抗性能的影响

Influence of textile structure on impedance of textile-structured electrodes

织物结构对纺织电极的性能有较大影响,为了给可穿戴医疗监护服装中纺织结构电极产品的设计提供理论参考,以镀银纱线作为原材料,采用织物结构单元成型的方式,通过织物结构分析模拟并结合电化学阻抗谱分析,分别研究了纱线屈曲状态、织物组织、织物密度、纱线连续状态及纱线数量对电极阻抗性能的影响。结果表明:相同长度的纱线在织物中的屈曲状态对电极阻抗性能影响较小;织物密度对电极阻抗性能的影响较小;纱线连续状态及纱线数量对电极阻抗性能的影响较大。

The key factors influencing the impedance of textile-electrolyte interface are analyzed using the basic structural fabric element simulation based on silver yarns. Electrochemical impedance spectrum method is used to investigate the interface of the system. The influence of yarn bending and interlocking state, structures, fabric density, yarn continuous state and yarn number on impedance is investigated theoretically and experimentally. It could be concluded from the results that bending and interlocking states of fiber and density of fabric exhibit minor effects on impedance. The yarn continuous state and yarn number show greater impact on the electrode impedance. Therefore, it can provide a basic principle for the design of the textile-structured electrodes for wearable medical monitoring clothing.
