Influence of textile structure on impedance of textile-structured electrodes

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.
