Abstract

This paper presents a new type of wearable textile-structured electrode for acquisition of human body bio-potential signals such as ECG, EEG and EMG. Various material systems and textile structures were selected and investigated. A range of textile electrodes made of brush-like embroidered, woven, knitted fabrics were fabricated and examined according to the performance requirements of a low impedance in the relevant frequency range and minimum motion-induced noise etc. Surface coating of silver chloride on the textile fibers was also studied. The noise caused by the relative movement between the electrode and simulated skin is also analyzed with controlled pressure, motion speed/pattern etc. Various textile electrodes were evaluated together with a commercial disposable gel electrode. The experimental results indicate that deposited silver-silver chloride material system on embroidered "brush-like" textile structure is the best design among all the electrodes investigated.
