柔性应变传感器件可以作为智能纺织的敏感元件，在运动监测、医疗康复等领域有广泛的运用。本文以针织面料作为基布，通过印花方式涂覆导电复合材料制成具有应变传感功能的导电面料，并对其加工工艺进行分析优化，对影响其传感性能的因素进行分析测试，制得了弹性模量低于0.5 Mpa，变形能力远大于20%且能重复使用的导电面料，可以嵌入服装中作为传感器敏感元件使用。%Flexible strain sensors can be used as sensitive elements in smart textiles and widely applied in sports monitoring, rehabilitation, etc. In this paper, knitted fabric was used as substrate material and it is coated with conductive composites by printing method to produce conductive fabric with strain sensing properties, and the process was optimized, the factors that influence the performance of the conductive fabrics were analyzed. The optimized conductive fabric can be embedded in garment as sensing element for repeat use with a tensile modulus less than 0.5 MPa and strain higher than 20%.
