Study on performance of bidirectional strain sensor of silver nanowire flexible fabric
摘要
Abstract
To develop a flexible fabric strain sensor with both tensile and compressive sensing property,a strain sensor with tensile/compressive bidirectional sensing properties was obtained by using silver nanowires as conductive material and cotton spandex double rib knitted fabric as flexible substrate,the two were assembled together by a dipping method.By testing the changes in resistance during stretching and compression,the bidirectional sensing performance of the strain sensor was thoroughly investigated.The results showed that in 100 cycles of stretch-release and compression-release,the relative resistance change offset rate of the flexible strain sensor was below 4%and 3%,respectively.The response time during the stretching process was 1.23 s,the peak time was 0.64 s,and the response frequency was 1 s.The response time during the compression process was 0.59 s,the peak time was 0.47 s and the response frequency was 0.12 s.The flexible strain sensor exhibited better sensing stability and reproducibility in both stretching and compressing states,higher resolution accuracy,a better linear relationship between relative resistance and strain or pressure,and a better response to external stimuli.It was capable of real-time monitoring of human body movements.It is considered that the prepared flexible pressure sensor has potential application value in wearable controllers and motion detection.关键词
