A PZT (lead zirconate titanate) element including one or more outside surfaces including a layer of encapsulation and metallization material and the method of making the same including at least the steps of providing a wafer of ceramic material including a base and one or more walls defining one or more recesses in the wafer which are filled with an encapsulation material. The encapsulation material is then cured and a layer of metallization is applied to one or more of the outside surfaces of the wafer and encapsulation material. Cuts are then made through the layer of metallization and cured encapsulation material to divide the wafer into a plurality of individual and separate ceramic elements with one or more surfaces including a layer of metallization and encapsulation.

Encapsulated ceramic element and method of making the same

A piezoelectric assembly includes a piezoelectric substrate that has a top surface, a bottom surface, and at least one side surface. A top electrode is defined on the top surface and a first aperture is defined in the top electrode. A bottom electrode is disposed on the bottom surface. The electrodes are formed from a thin film metal. A first thick film bond pad is disposed in the first aperture and is in contact with the piezoelectric substrate. The first thick film bond pad is in electrical contact with the top electrode. In further embodiments, a second thick film bond pad is disposed on either the top surface or in a second aperture defined in the bottom electrode.
