Abstract

Piezoelectric actuator can be used for handling the miniature parts through a micro gripper for micro assembly where study of stable displacement and force characteristics with voltage are important. For obtaining these behaviors, electromechanical characterization of piezo actuator is required. In this paper, design and analysis of piezoelectric actuator for micro gripper is carried out by using combination of two piezo ceramic layers and one resistive layer between them where the voltage (±60 V) is supplied and controlled through a proportional-integral-derivative (PID) controller. Experimentally, it is found that the piezoelectric actuator produces maximum deflection up to 1.5 mm and generates maximum force up to 0.203 N. A piezoelectric actuator based micro gripper is developed for demonstrating the micro assembly.
