Abstract:
1. At least one piezoelectric element arrangement comprising: at least one deposited, poled and tested piezoelectric element structure having a thickness of 10 μm to 100 μm formed by a deposition process directly on a first substrate, wherein the piezoelectric element structure and the first substrate are comprised of materials which permit removal of the piezoelectric element structure from the first substrate by a laser lift off process, the piezoelectric element structure being physically separate and apart from the first substrate on which the piezoelectric element structure was deposited and formed; a first electrode deposited on a first surface of the piezoelectric element structure; and a second electrode deposited on a second surface of the piezoelectric element structure, wherein the at least one piezoelectric element structure is bonded directly to a target substrate by a bonding layer, the target substrate comprised of a material which will cause the target substrate to be destroyed and rendered inoperative at temperatures reached in a preparation process used to make the poled and tested piezoelectric element structure, and wherein the bonding layer is formed by bonding materials which include at least one of nonconductive epoxy bonding material containing conductive particles, nonconductive epoxy bonding material alone, or thin film metal bonding material.
