Abstract
A piezoactuator includes a base. The base contains a stack of piezoelectric layers and electrode layers interspersed among the piezoelectric layers. The piezoelectric layers contain a ceramic material; the piezoelectric layers and the electrode layers are sintered together; and the base has a hole therethrough. The piezoactuator also includes a contact element, such as a pin, in the hole. The contact element is for use in forming an electrical connection to at least some of the electrode layers.
