Dimensional change of paraelectric materials influenced by an electric field
Piezoelectric actuators and sensors
Deformed under mechanical stress, Piezo crystals become electrically charged.
The same materials undergo dimensional change under the influence of an electric field.
The piezoelectric effect is the ability of certain crystalline materials to convert mechanical stress into electrical signals and vice versa. Every Piezo Sensor can also be used as a Piezo Actuator. The industrially most important piezoelectric materials consist of ferroelectric polycrystalline ceramics. These piezoelectric materials possess a Perowskit crystalline structure.
