Conductive polymer based fiber electrode for vital condition analysis

Abstract

Long-term measurement of vital conditions is essential for analysis of health conditions. For this purpose, it is required for high biocompatibility of sensing devices without having skin irritations. As ambient measurement is ideal, wearable approaches could be one of the solutions. Here we use conductive polymer based fiber electrode for analysis. The silk/washi fibers was treated with PEDOT-base conductive polymer. Treatment with conductive polymer does not alter the characteristic of the base material, such as flexibility and texture. We use this electrode for ECG, EMG and ECoG measurement. We have been developing the usage of this electrodes for various kind of fields including medical and others. Establishment of research community, flexible-silk-electrode research, was helpful for promoting the research and forming spin-out business. Interaction with various field researchers are extremely important for developing new technologies and materials. Recent activities will also be reported.
