Abstract: 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.

Key words: tri-axial micro-force sensor, micro-gripper, piezoelectric actuator, finite element analysis
