Piezoelectric Actuators for Compliant Mechanisms

The growing demand for precision and miniaturization in micro-scale systems and biomedical applications has driven the need for highly optimized compliant mechanisms. The design of these mechatronic systems requires advanced actuators optimization, synchronizing material characteristics, geometric limitations, and mechanical structure. This study presents analysis results, emphasizing the performance of piezoelectric actuators for compliant mechanisms. Analytical results were presented for two types of actuators: stack actuators and bending actuators. We examined displacement when a different voltage was applied and designed a mini gripper as an application. Finally, experimental results for stack and bending piezoelectric actuators are presented. This study provides a solid framework for integrating simulation findings with experimental requirements in the compliant mechanisms field.
