Abstract [en]

Textile-based electrodes show great potential as substitution of conventional electrodes when long-time monitoring is required. The flexibility and high skin-electrode contacting area make it possible to avoid the use of contact gel, which may cause irritation to the patients' skin. In this study, textile-based electrodes were made by combining conductive materials with high absorption nature fibres with the intention to create and maintain a microenvironment that improve the contact between the skin and electrode by local sweating at the electrode site. Alternatively artificial sweat (i.e. saline) may be added for a similar effect. However, by adding nature fibres into the electrodes, the electrical properties of the electrodes are modified due to the ration of conductive yarns is decreased. In this paper, the surface resistivity in the warp and weft directions and its distribution were measured in a four-wire resistance mode. The resistivity of the conductive yarns, the type of nature fibres, the textile construction and the fabric pick density were selected as the independent variables and the surface resistivity in warp and weft measurement directions was the dependent variable to be analysed. Preliminary results show that the conductivity of the conductive yarns are more important than the fabric pick density; surface resistance were not measurable in warp direction of most plain weave fabrics since the conductive yarns were only involved in the weft direction, however, the resistance were measureable in the case of satin fabrics; and that the surface resistivity is more evenly distributed in weft direction than the warp direction
