Piezo-ceramic materials are categorized as functional ceramics. In sensors they make it possible to convert forces, pressures and accelerations into electrical signals, and in sonic and ultrasonic transducers and actuators they convert electric voltages into vibrations or deformations. Piezo-ceramic materials are classified according to their chemical composition on the one hand, and by the specific application conditions on the other.
Materials for power transducers (ultrasonic applications)
Materials for sensor applications (ultrasonic transmitters and receivers)
Materials for actuating applications (precision positioning or injection systems)
