The experimental research of piezoelectric actuator with two vectors of polarization direction (original) (raw)

This research investigates the performance of a novel piezoelectric actuator designed with two vectors of polarization. By employing specific electrode patterns, the actuator achieves independent movement in three degrees of freedom (3-DOF), allowing precise control of contact point trajectories. Experimental results reveal the resonance characteristics of the actuator and validate the proposed excitation schemes, demonstrating notable efficiency in multi-DOF applications and potential applications in advanced mechatronic systems.
