摘　　要：针对可穿戴智能纺织品对于柔性可拉伸传感元件的需求,探讨柔性应变传感器在人体运动监测领域的可行性。以下肢跑步运动为例,选取大腿前中、大腿外侧偏上以及膝上3个位置放置柔性传感器,对跑步运动进行监测,利用传感器采集到的应变-电阻变化信息获取人体下肢运动状态。运动测试结果表明,随着人体跑步运动速度的变化,柔性传感器产生不同的拉伸变形,传感器应变-电阻变化与实际体表拉伸产生的形变趋势相同,其中放置于不同位置上的传感器产生的电阻变化差异能够较好地用于表征人体下肢运动强度、运动周期数等。完成了智能跑步运动裤的基础原型制作,并验证了可穿戴式柔性传感器用于人体下肢运动监测的可行性。Aiming at the current demand of wearable smart textiles for flexible stretchable sensing elements,the feasibility of flexible strain sensor in monitoring human motion was discussed. Taking the human lower limb running exercise as an example,the flexible sensor was placed on the front side of the thigh,the lateral side of the thigh and the knee,and the static and dynamic running motions of the human body were monitored respectively. The strain-resistance information was collected by the flexible sensor to gain the human body behavior status. The results showed that with the change of running speed,the flexible sensors produced different tensile deformation. The strain-resistance change of the sensor was the same as that of actual body surface tension. The difference of resistance changes generated by the sensors in different palaces could be better used to characterize exercise intensity and the number of motion cycles. Finally,the basic prototyping of smart running pants was made,and it was verified that wearable flexible sensors could perform human lower limb motion monitoring.
