Reducing backward motion of stick-slip piezoelectric actuators using dual driving feet designed by asymmetric stiffness principle
Stick–slip piezoelectric actuators (SSPEAs) have drawn attention for their features of simple
structure and high positioning accuracy. However, the backward motion has always been a …
