ABSTRACT:
A relatively stiff piezoelectric translator comprises at least a pair of piezoelectric devices joined together at one end and secured to a fixed support at their other ends in orthogonal directions. Displacement of one device along its longitudinal axis displaces the other devices in a relatively weak direction transverse its longitudinal axis. Stiffness is enhanced by securing both ends of each device in the system.
