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 cornerstone 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 flexure-guided nanopositioning systems and piezo linear motors. All piezoelectric drives are ceramic-based, and can operate in a vacuum; they do not produce magnetic fields nor are they influenced by them.
It is actually difficult to differentiate the market between piezoelectric operated motors and piezoelectric operated actuators as these variants are used for same application in common products. For example in a digital camera, the auto-focus mechanism uses a piezoelectric operated motor but in camera phones, the same mechanism is operated by piezoelectric operated actuators.
Commercialization of piezoelectric operated actuators and motors is likely to proceed in those markets where the specific advantages of high torque, high precision and lack of magnetic interference are particularly useful. When the costs can be lowered to competitive levels and remaining technical problems such as frictional wear can be solved, piezoelectric motors may also become candidates in areas such as automotive accessories, where very high volume markets are possible.
