3.4.2 Piezoelectric system

A piezoelectric ceramic element is an artificially polarized wafer which deforms when an electric field is applied across its surface. The magnitude of the strain is directly proportional to the magnitude of the applied electric field. The system is constituted by stacking several piezoelectric elements to extend the range of displacement. The system was used in the University of California at Davis.
