Multilayer Actuators:

Monolithic multilayer actuators function is based on the piezoelectric effect. A piezoceramic material expands in the direction of the electrical field when a voltage is applied to it. The field strengths required to produce this phenomenon are approx. 2000 V/mm. Our actuators are produced using a specially developed stacking and sintering technology from layers of ceramic material about 0.1 mm thick. Therefore, a fairly low voltage can achieve maximum displacement.
