Patent ID: 7388319

Claim:
A microelectromechanical device, comprising: a body having a plurality of chambers; a plurality of pre-fired piezoelectric islands supported by the body, wherein each of the piezoelectric islands has a first surface, a second surface opposing the first surface and a third planar surface interconnecting the first and second surfaces, wherein the piezoelectric islands have a surface that substantially includes grains of piezoelectric material having a width between about 2 and 4 microns and a plurality of recesses; and a conductive material on the first surface and a conductive material on the second surface of the piezoelectric islands, wherein the conductive material is in the plurality of recesses and contacting the piezoelectric material in the recesses; wherein at least one of the plurality of piezoelectric islands is positioned substantially adjacent to a corresponding chamber of the plurality of chambers; wherein at least one of the piezoelectric islands has a conductive material on the third surface, the conductive material on the third surface electrically contacting the conductive materials on the first and second surfaces.
