An Integrated Piezoelectric Inertial Actuator Controlled by Cam Mechanisms

This paper presents a battery-supplied piezoelectric actuator controlled by cam mechanisms. The actuator moves by matching the phase difference between the clamp and the excitation cams. The piezoelectric bimorphs of the actuator are excited by signals from a contact switch driven by the excitation...
