Piezoelectric device and method to manufacture a piezoelectric device

摘要

A piezoelectric device is formed of a supporting substrate with first and second conductive traces on a first surface. A piezoelectric material layer is laminated to the supporting substrate with a first surface of the piezoelectric material layer electrically connected to the second conductive trace and a second surface of the piezoelectric material layer electrically conducted to the first conductive trace. A protective coating is applied over the piezoelectric material layer so that at least a portion of the first and second conductive traces are exposed.
