Electrodermal Responses Through Textile Electrodes Available to Purchase

This paper aims at testing the ability of textile electrodes to effectively acquire electrodermal responses (EDRs). EDRs are acquired from sixteen healthy subjects in order to comparatively evaluate the performance of textile versus standard silver/silver chloride (Ag/AgCl) electrodes. The acquired signals are analyzed in the time and frequency domain, and a statistical approach is used to validate the system. Moreover, a characterization of a textile electrode, in terms of electrode impedance measurement and a current/voltage diagram, is carried out in the frequency range of EDR usability (from 0.01 Hz to 2 Hz). The results show good performance.
