Piezo-ceramics in Sensors and Power Transducers

Advanced Ceramics Expertise in Piezo Applications

Piezo-ceramic components are electromechanical transducers: They can convert mechanical energy into electrical energy and vice-versa. They are also used in sensors and power converters for high-power ultrasound applications. 


Piezo-ceramic components from CeramTec are used in a variety of electromechan­ical transducers in a wide frequency range.

Piezo-ceramics are used to convert mechanical parameters, such as pressure and acceleration, into electrical parameters or, conversely, to convert electrical signals into mechanical movement or vibration.

In sensors they make it possible to convert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers to convert electric voltages into vibrations or deformations.


Piezo-ceramic Applications

In automotive engineering sensors keep passengers safe and ensure intelligent engine management. In ultrasonic applications piezo-ceramic components generate great ultrasonic intensities for ultrasonic cleaning and drilling, ultrasonic welding or for stimulating chemical processes. Still other piezo-ceramic components are used as ultrasonic transmitters and receivers in many areas of signal and information processing applications.

Piezo-ceramic actuators function based on the fact that deformations can be generated in the micrometer range. This behavior opens up new application possibilities for electromechanical transducers as actuators for hydraulic and pneumatic valves, positioning systems, micromanipulators and dispensing systems for liquids and gases.

“Piezo-ceramic components enable ultrasonic local­ization in sonar technology, distance measurement, non-destructive material testing and medical diagnostics.”


Note: With the acquisition of the Electro-Ceramics Division from Morgan Technical Ceramics, CeramTec has broadened its range of materials and products. Please visit the new range of piezo-ceramic products too.
