Impact-Based Amplification and Frequency Down-Conversion of Piezoelectric Actuation for Small Robotics

Impact-Based Amplification and Frequency Down-Conversion of Piezoelectric Actuation for Small Robotics

This paper explores a concept for dynamic amplification of piezoelectric actuator motion using repeated impacts between the active transducer and a compliant amplification mechanism. The design shows good performance in amplifying vibration of a lead–zirconate–titanate (PZT) bimorph while down-conve...
