摘　　要：针对柔性触觉传感器存在的设计难度大、抗干扰性差、不易封装以及线路布置困难等问题,基于Storakers材料模型的应变能密度函数发展了一种基于石墨烯气凝胶(graphene aerogel,GA)的具有“气泡膜”结构的全柔性触觉传感器的设计方法.通过模拟分析发现,相对于“三明治”结构,“气泡膜”结构的GA柔性触觉传感器具有更好的抗干扰性.在此基础上,设计并组装了“气泡膜”结构的GA全柔性触觉传感器,通过实验证实该GA全柔性触觉传感器具有优异的传感特性、力学特性和抗干扰特性.同时,设计开发了压阻式传感阵列的信号采集系统,并成功实现了其对力的大小、物体位置和形状等信息的实时采集和传感监测.To address the concern of flexible tactile sensors,including hard design,packaging,circuit layout,and poor anti-interference,a feasible design method of graphene aerogel(GA)-based fully flexible tactile sensor is proposed based on the strain energy density function of Storakers material model.This method demonstrates that the GA-based flexible tactile sensor with a“bubble film”structure exhibits superior anti-interference performance compared to the“sandwich”structure.Thus,the GA sensor with a“bubble film”structure is fabricated,and its excellent sensing characteristics and mechanical and anti-interference properties are subsequently demonstrated using various measurements.Thus,the signal acquisition system of the piezoresistive sensor array is further designed and developed,along with the successful real-time monitoring of force,object position,and shape.
