Development of PZT and PZN-PT based unimorph actuators for micromechanical flapping mechanisms
(2001)Proceedings of the 2001 IEEE International Conference on Robotics & Automation (ICRA)This paper focuses on the design, fabrication and characterization of unimorph actuators for a microaerial flapping mechanism. PZT-SH and PZN-PT are investigated as piezoelectric layers in the unimorph actuators. Design issues for microaerial flapping actuators are discussed, and criteria for the optimal dimensions of actuators are determined. For low power consumption actuation, a square wave based electronic driving circuit is proposed. ...Conference Paper
