![]() Microelectronics – Mask positioning, microlithography, inspection and control systems.Ī piezoelectric actuator is an electrically controlled positioning element that functions based on the piezoelectric effect.Medicine – micromanipulation and microsurgery, cell penetration, microdosing systems, physiological stimulations, shock generation.Optics and measurement systems – employed in rapid scanning and positioning of mirrors, holography, interferometry, laser sweeping, fiber optics positioning, image stabilization, active adaptive auto focus.Precision mechanics and Mechanical engineering – found in adjust and extrusion tools, correction of wear and active control in tools injection nozzle control, micropumps, piezo hammers, micro etching, active vibration cancelling systems, micro and nanorobots.Such advantages have made piezo actuators very popular in several domains as: No magnetic fields are generated when the actuator is operating.Very low power consumption as the piezo effect converts energy directly into motion, the execution element absorbs energy only when elongating.Endurance tests have proved that there is no altering in such an actuator’s operation even after 500 million cycles Elongation of a piezoelectric actuator is based only on deformation of the material and there is also no fatigue or aging involved. There are no moving parts and thus no friction or free play.Accelerations several thousand times higher than gravitational acceleration (G) can be attained ![]() As an example, the elongation response of a piezoelectric actuator can be limited only by the speed at which sound is propagated through ceramic materials.
