模具固化成型法弹性电极的制作
|
摘要
为了解决用于机器人触觉感知的柔弹性电极导电稳定性差、柔弹性不够、易被磨损破坏等问题,基于银纳米线及聚二甲基硅氧烷采用模具固化成型方法设计制作了长条形弹性电极,并进行了拉伸试验。结果表明:拉伸后的电阻增量为电阻初始值的380%,且多次拉伸后,电阻波动值都很小,这种弹性电极保持了良好的导电性和导电稳定性,可以应用于拉伸、弯曲、扭转等多种复杂的应用场合。
In order to solve the problems of poor electrical stability,insufficient flexibility,and wear and tear of flexible electrodes used for tactile sensing of robots,a long strip was designed based on silver nanowires and polydimethylsiloxane using a mold curing method.The elastic electrode was shaped and subjected to a tensile test.The results show that the increment of the resistance after the stretching is 380% of the initial value of the resistance,and after a plurality of times of stretching,the fluctuation value of the resistance is very small.This kind of elastic electrode maintains good conductivity and conductivity stability,and can be applied to Stretching,bending,twisting and other complex applications.
