Piezoelectric tuning device and method for making the same

Abstract From the Canadian patent

A piezoelectric tuning device having a thin piezoelectric plate which has a pair of electrodes thereon and conductive means extending therefrom. The surface of the electrodes are covered with thin films and electrical load terminals are connected to the conductive means. The thin piezoelectric thin plate covered with the thin films embedded in a plastic body without an air space between the plastic body and the thin plate and the ends of the electrical terminals extend through and out of the plastic body. This tuning device has excellent electrical and mechanical properties.
