摘　　要：为提高镀银尼龙纱线制备的柔性传感器的环境稳定性,提升传感器集成于服装的效率,本文提出新的设计理念:基于同轴湿法纺丝技术制得以尼龙(PA)纱线为芯层、聚氨酯(TPU)和炭黑(CB)复合材料为皮层的芯鞘结构的TPU/CB/PA导电纱线,使用此导电纱线在成品弹性带上缝制方波形、锯齿形两种重复图形,制备5种柔性应变传感器.文章探究了缝制图形的图案、数量、图形间距等参数对传感器性能的影响,结果表明:图案数量增加能提升传感器的稳定性和灵敏度;方波形传感器的稳定性优于锯齿形的;2#传感器样品在0%~10%应变内有良好的线性度和稳定性,具有呼吸监测的潜力.In order to improve the poor environmental stability of flexible sensors prepared from silver-plated nylon yarns and to enhance the efficiency of sensor integration into garments,this paper proposed a new design concept:based on the coaxial wet-spinning technology,a core-sheathstructured TPU/CB/PA conductive yarn with nylon(PA)yarn as the core layer and polyurethane(TPU)and carbon black(CB)composite as the skin layer was prepared,and the conductive yarn was used to stitch two repetitive patterns of square waveform and saw-tooth shapes on the finished elastic This conductive yarn was used to sew two kinds of repeating patterns,square wave and saw-tooth,on the finished elastic tape to prepare flexible strain sensors.This paper explored the effect of graphs,number of graphs,and graph spacing on the performance of the sensors.The results show that an increase in the number of patterns of the sensor enhances the stability and sensitivity of the sensor.The stability of the sensor with square waveform pattern is better than that of the sensor with saw-tooth pattern.The sensor sample of 2#has good linearity and stability within 0%to 10%strain and has potential for respiratory monitoring.
