Piezoceramic actuators use the effect of the relative change in length (up to approx. 1.5 0/00) when an electric field is applied. They are characterized in particular by high mechanical load capacities (up to 100 MPa), extremely low power dissipation or very low energy loss (zero current when not moving), short response times (in the submillisecond range), extremely high motion resolution (in the subnanometer range) and high reliability (more than 1010 switching cycles).
