Basic Study of Weaving Structure and Durability for Fabric-type ECG Sensor Design

Abstract Recently, study of functional clothing for vital sensing is focused on improving conductivity and decreasingresistance, in order to enhance the electrocardiogram(ECG) sensing accuracy and obtained stable environmental durab ility onoperation condition. In this study, four ECG fabrics that having different componnt yarns and weaving structures were produced toanalyze their environmental durabilities and electric properties under general operation cond itions including different physical andchemical stimulation. For outstanding electric properties and physical properties, the optimized ECG sensing fabric should consist ofa fabric of 2 up 3 down twill structure containing 210de silver-coated conductive yarns and polyester yarn in warp and weftdirections respectively. The selected fabric has 0.11 which is relative lower resistance than otherwisely produced fabrics underΩECG measurement condition. And it has 7% stable resistance changes under 25% strain and repeated strain. Keywords:
