摘　　要：设计了一种集成三维力传感器微夹持器,通过压电陶瓷堆驱动和柔性铰链放大来实现夹持动作.微夹持器的弹性体为2个L型结构,对L型结构进行了优化设计和受力仿真分析,在2个L型结构的相应敏感部位分别粘贴3组应变片对空间三维力进行测量.通过试验验证了微夹持器的合理性和实用性.A novel micro-gripper integrating tri-axial force sensor was introduced, and the clamping motion was realized through piezoelectric ceramic stack actuation and flexible-hinge enlargement. Its elastomeric body is two L structures. The L structure was optimized and simulated with suffering force. The strain gauge was sticked at L structure sensitive position to measure tri-axial force. The experiment verified the micro-gripper＇s rationality and practicability.
