基于相关的国家标准,类似工业产品以及其用途对织物应变传感器的性能指标进行评价,采用松弛时间和反应时间作为评价大应变型传感器的指标.并给出关键性能的评价方法,这些评价方法也适用于其它类型的织物应变传感器.基于这些评价方法,对新开发的织物应变传感器进行了测试,结果表明,该传感器能在20%的应变范围内稳定工作,同时具有高灵敏度(应变系数约43),低滞后(6.25%),相对短的松弛时间和反应时间,以及良好的重复性和线性度.该传感器有望在医用、运动服装以及康复治疗等方向得到应用.

The performance specifications of fabric strain sensors were presented based on corresponding standards, commercial products of other sensors and application of the sensor. General evaluation methods were given for key characteristics such as sensitivity, linearity, repeatability, hysteresis, etc. , moreover, relaxation and responding time were adopted to evaluate sensors for large strain measurement. These evaluation methods can be used for performance evaluation of other fabric strain sensors. New fabric strain sensor developed by our group was characterized based on these methods. It shows that the sensor can stably measure strain up to 20% with a relative high sensitivity (gauge factor about 43), small hysteresis (6. 25%), relative short relaxation time and short responding time as well as good repeatability, linearity; it has a lot of application potentials in electrotherapy treatment, sports and rehabilitation.
