Short term variation of resistivity of conducting polymers and its dependence on electric field

Conducting polymer materials have received attention in recent years as they exhibit unique characteristics such as electrical conductivity and flexibility which make them suitable for use in biomedical and electronic applications. They can be used as strain gauges with greater flexibility compared to metal and semiconductor strain gauges. In the course of developing a strain gauge, understanding of electrical characteristics of conducting polymer is essential and some aspects are presented in this paper. Preliminary investigations on PEDOT-PSS thick films have shown that its AC resistance is fairly stable compared to DC resistance.
