1. A method of manufacturing a piezoelectric package, comprising:
- disposing a first composite sheet relative to a first electrically conductive sheet;
disposing a first planar surface of a piezoelectric plate relative to the first electrically conductive sheet;
disposing a second electrically conductive sheet relative to a second planar surface of the piezoelectric plate opposite the first planar surface;
disposing a second composite sheet relative to the second electrically conductive sheet, wherein a laminate structure of the first and second composite sheets, the first and second electrically conductive sheets, and the piezoelectric plate is formed; and
heating the laminate structure, wherein the first and second composite sheets polymerize in response to the heating to transform the laminate structure into an integrated composite structure, and the first and second electrically conductive sheets are respectively electrically coupled to first and second planar surfaces of the piezoelectric plate.

Abstract
A piezoelectric package comprises a piezoelectric plate having a first planar surface and a second planar surface that are electrically isolated from each other. The piezoelectric package further comprises a first electrically conductive layer electrically coupled to the first planar surface, and a second electrically conductive layer electrically coupled to the second planar surface. The piezoelectric package further comprises a first electrically insulative material (e.g., a rigid fiber composite material) encapsulating the piezoelectric plate and at least portions of the first and second electrically conductive layers.
