Research on Wearable Sensors Based on Knitted Fabrics with Silver Plating Fiber

Article Preview

Abstract:

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.
