随着智能机器人的发展，具有精准压力感知能力的电子皮肤成为研究热点。本文使用改性多壁碳纳米管(MWCNTs)和硅橡胶(SR)组成的复合材料及三聚氰胺海绵，采用浸渍工艺，制备了一种高灵敏电阻式柔性压力传感器。阐述了传感器的制作流程，对多壁碳纳米管的改性进行了表征，测试了压力传感器的传感性能，并将传感器装配到机械手上实时检测压力。测试结果表明：制备的海绵压力传感器具有良好的稳定性，宽工作范围(0～580 kPa)
快速的响应时间(～46 ms)及良好的重复性(～2 000次)。将传感器装配到定制的3D打印机械爪模具中安装到机械臂上，通过设计的信号采集电路及编写LabVIEW
上位机可以实时获取传感器的信号，得到机械爪上的压力数据，并结合支持向量机算法实现对抓取物体的分类。
