Piezoceramics

Piezoceramic materials generate charge separation under the influence of a mechanical force; when the material is deformed, electrically charged regions are formed. These functional materials have extremely short response times and, in addition to the quasi-static range, can also be used to excite high-frequency vibrations up to the gigahertz range. Piezoceramics are already used as standard in the automotive industry, for example as injectors for fuel-efficient diesel and petrol engines, and in medical technology as ultrasonic sensors.
