The outstanding performance potential of PIEZOCERAMICS

Basic properties, application areas, technology chains, and commercial piezoceramic materials

Piezoceramics are poled ferroelectric ceramic materials showing the effect of strong electro-mechanical coupling.

  • Applied electrical voltages cause shape chances of piezoceramic bodies. They are becoming longer or shorter depending on the polarity and the strength of the electric field. The magnitude of deformation is relatively small (about 0,1% of device dimension). Piezoceramic devices respond very fast with response time < 100 µs. Vibrations up to MHz – range are possible under cyclic loads.
  • Mechanical impacts generate electricity at the electrodes. Real devices can produce voltages in the kV range. Piezceramic devices are roboust, durable and long term stable. They can further processed to composites with other passive materials by specific technologies (lamination, moulding, screen printing …).

Mechanically hard and soft device designs are on the market. Piezoceramics are the key functional materials of actuators, sensors, generators, transformers and acoustic transducers.Standard products are cost-effective.
