A low-profile flexural displacement-converter mechanism for piezoelectric stack actuators
Sensors and Actuators A: Physical, 2020 A thin flexure-based mechanism is proposed that is useful in applications with limited build space. The proposed mechanism converts the initial in-plane motion of two piezoelectric stack actuators to an out-of-plane translational motion. Two actuators in the symmetric design of the proposed APA can be used to ensure a pure translation output motion.
