摘　　要：基于聚丙烯压电驻极体(Piezoelectret)设计了一种应用于人工皮肤的触觉传感器。该传感器具有柔性良好、压电效应稳定、制备简单、成本低廉等特点。通过触压、滑动、同时触压与滑动、恒定力重复触压等实验,可观察到该传感器对不同触觉信号具有明显的特征差异,且阵列传感器的信号检测稳定性比单路传感器高40%。将该传感器置于假肢手指前端反馈触觉信号,并根据触觉信号调控假肢手的抓握力,可实现对易脆和光滑物体的稳定抓握。A tactile sensor for artificial skin was designed based on polypropylene piezoelectret. The piezoelectret sensor has such advantages as good flexibility, stable piezoelectric effect, easy fabrication, low cost. The sensors showed obviously different characteristics upon pressure, slippage, simultaneous pressure and slippage, and repeated constant pressure tests. In addition, the signal stability of the array sensors was 40% higher than that of single -channel sensors. The sensor was mounted on the finger of a prosthetic hand. By adjusting the grasp force according to the tactile information, stable grasp of fragile and slippy objects could be realized.
