Piezoelectric Facts
- The term “piezo” is derived from the Greek word for pressure.
- The piezoelectric effect is often encountered in daily life, for example in lighters, loudspeakers and buzzers.
- Piezo technology has recently established itself in the automotive branch.Piezo-driven injection valves in diesel engines require much lower transition times than conventional electromagnetic valves, providing quieter operation and lower emissions.
- Piezo actuators require no maintenance and are not subject to wear because they have no moving parts in the classical sense of the term.
- Piezo actuators present capacitive loads and dissipate virtually no power in static operation.
- Piezo actuators can move high loads, up to several tons.
- Piezo actuators can perform sub-nanometer moves at high frequencies because they derive their motion from solid-state crystaline effects. They have no rotating or sliding parts to cause friction.
- Actuators using the Piezo effect have been commercially available for 35 years and in that time have transformed the world of precision positioning and motion control.
- The first commercial applications of the inverse piezo effect were for sonar systems that were used in World War I.
