Investigation of Mechanical and Electrical Properties of E-textile Bioelectrode Consisting of Conductive Polymer and Ionic Liquid Gel on Knit Fabric

抄録

We developed an e-textile bioelectrode composed of knit fabric coated with a conductive polymer and ionic liquid gel and evaluated its mechanical and electrical properties. We found that the electric resistance of the e-textile bioelectrode could withstand up to 30% stretching owing to the structural change in the knit fabric. We also found that the mechanical stress of the knit fabric with bioelectrode materials could be increased to 50 N at 100% stretch, while the stress of knit fabric was 10 N. This bioelectrode can also be used without any increase in electric resistance up to 30% stretch in a 1000-times cyclic test. The resultant mechanical and electrical properties can be used as a standard for e-textile bioelectrodes on knit fabrics.
