摘　　要：为制备呼吸监测智能服装用针织结构柔性传感器,首先通过等离子体对双经平结构的涤纶经编织物进行预处理,然后利用原位聚合法进行导电处理,分析了导电经编织物的微观结构与导电性能、应变-电阻传感性能,并探讨了其在呼吸监测智能内衣中的应用。结果表明:原位聚合法导电处理可赋予涤纶经编织物良好的导电性能,织物的电阻率较未处理时降低了约11个数量级;导电经编织物具有良好的应变-电阻传感性能,往复拉伸后电阻变化保持稳定,在6%和10%的应变条件下,其敏感因子分别为6和4左右;导电经编织物传感器具备良好的人体呼吸监测能力,不仅能记录呼吸的发生,还可监测呼吸的频率及强度。For preparation of knitted flexible sensor for respiratory monitoring in smart clothing,a two-bar tricot polyester warp-knitted fabric was pretreated by plasma followed by in-situ polymerization treatment for conductivity.The structure,electrical conductivity and strain-resistance sensing property of conductive warp-knitted fabric was investigated,and its application in respiratory monitoring smart underwear was also discussed.The results show that conductive treatment of in-situ polymerization gives the polyester warp-knitted fabric good electrical conductivity,and the resistivity of the fabric is about 11 orders of magnitude lower than that of the untreated.The resistance of conductive warp-knitted fabric decreases during stretching and recovers when shrinking,which shows good strain-resistance sensing characteristics.After a long time of reciprocating stretching,the resistance changes of the conductive warp-knitted fabric remain stable,and the gauge factors are about 6 and 4 at 6%and 10%strain conditions,respectively.The conductive warp-knitted fabric sensor demonstrates good ability to monitor human respiration,which can not only record the occurrence,but also monitor the rate and intensity of respiration.
