Abstract
New applications are emerging for piezoelectric operated actuators and motors in applications including aircraft, automobile hydraulics and drug delivery. Among piezoelectric devices, piezoelectric actuators produce a small displacement with a high force capability when voltage is applied. They are used mainly in ultra-precise positioning and in the generation and handling of high forces or pressures, whereas piezoelectric motors use a piezoelectric ceramic element to produce ultrasonic vibrations in a stator structure. The elliptical movements of the stator are converted into the movement of a slider that is pressed into frictional contact with the stator. Depending on the stator' s design, the resulting movement can be either rotational or linear.
The virtually unlimited resolution and extremely fast response of piezo devices have made them a corner stone of ultraprecision applications from nanometrology to nanomanipulation. Today a large variety of piezo-based positioning systems is available, from simple open-loop actuators, to complex fl exure-guided nanopositioning systems and piezo linear motors. All piezoelectric drives are ceramic-based, and can operate in a vacuum; they do not produce magnetic fi elds nor are they infl uenced by them.
