The operation of the piezo ceramic actuator is characterized by four factors: a) precision; b) speed; c) high force and d) relatively short displacement. Since the positioning precision is derived from molecular effects, if is free of stiction and friction which allows controllability down into the sub-nanometer range if desired. On the other hand, high force motion can be exerted in micro-seconds. This is why piezoelectric mechanisms are at the heart of the latest generation fuel injection valves as well as in today’s semiconductor lithography tools, super-resolution microscopes and a variety of other nanoscale-precision metrology and positioning systems.
