摘要
为了解决应变传感器制造成本高、制备工艺复杂的问题,本文采用蜡烛火焰燃烧法制备了具有导电性的纳米烟灰颗粒,并通过热压-剥离工艺将烟灰颗粒转印到苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物(styrene ethylene butylene styrene,SEBS)表面,制备了蜡烛烟灰/SEBS柔性传感器,同时对其力学性能和传感特性进行表征测试。测试结果表明,该柔性传感器具有良好的柔韧性;在一定范围内,传感器的相对电阻与应变成线性关系;同时,应变传感器在经过1000次循环机械拉伸后,仍然保持良好的传感性能。将蜡烛烟灰/SEBS应变传感器应用于人体运动检测,可以实时监测手指和手腕的弯曲运动。该研究对于制备低成本柔性应变传感器具有良好的应用前景。
In order to solve the problems of high manufacturing cost and complicated manufacturing process of strain sensors,the candle flame burning method is adopted to study the flexible strain sensor of candle soot.The soot particles are transferred to the surface of the styrene-ethylene-butylene-styrene block copolymer(SEBS)through the hot pressing-stripping process,and the SEBS/candle soot flexible sensor is prepared and the mechanical and sensor properties are tested for characterization.The test results show that the prepared sensor has good flexibility;the strain has good linearity with respect to the change of relative resistance;at the same time,the strain sensor still maintains good sensing performance after 1000 cycles of mechanical stretching.The SEBS/candle soot strain sensor is applied to human motion detection,which can monitor the bending motion of fingers and wrist in real time.The research has a good application prospect for the preparation of low-cost flexible strain sensor.
