Durability study of e-textile electrodes for human body communication

Abstract

The purpose of this study was to investigate the durability of e-textile electrodes for use in human body communication. Two types of e-textile electrodes were fabricated: a woven copper nickel-plated cotton and a knit jersey consisting of 63% cotton, 35% silver yarn, and 2% spandex. The signal transmission and surface resistivity of each type of electrode were initially measured as a control group. Subsequently, sets of each electrode were exposed to various durability tests in accordance with standards established by the American Association of Textile Chemists and Colorists and the American Society for Testing and Materials. The results of these tests were used to evaluate the durability of the electrodes, and the effects of the durability tests on the surface resistivity and signal transmission characteristics were analyzed and discussed.
