摘要：
In order to prepare yarn-based strain sensor, the twisted silk filaments were woven into a closed chain stitch structure. Silver nanowire was prepared by reducing silver nitrate with polyol, base yarns were impregnated in an ethanol dispersion of the silver nanowires for conductivity modification. The strain-resistance sensing performance of the yarn-based strain sensor was studied. The results show that the yarns with the chain stitch structure have excellent strain sensing performance, the yarn resistance decreases with the increase of the strain. When the tensile strain is less than 5%, the gauge factor of the strain sensor is up to 20.14. The sensor has stable response in the tensile frequency range from 0.01 Hz to 1.00 Hz, and also has good cycle stability. Copyright No content may be reproduced or abridged without authorization.
