Research on Wearable Sensors Based on Knitted Fabrics with Silver Plating Fiber
Two kinds of plain fabrics, made of silver plating yarn, were tested on conductivity under weft extension to investigate the relationships between tensile property and resistance. The results are following: the resistances of two kinds of fabrics have a linear relationship with strain within a definite range; the strain sensitivity of the inelastic plain fabric is smaller than that of the elastic plain fabric; the changes of contact resistance of the overlapped yarns cause the inelastic plain fabric sensitive to strain; when two kinds of fabrics were stretched repeatedly to simulate heartbeat signals, their resistance remained stable at a value. So they satisfy stability requirement.
