Patent ID: 7574787

Claim:
A method of producing at least one piezoelectric element comprising: depositing a piezoelectric ceramic material onto a first surface of at least one first reusable single layer substrate structure to form at least one piezoelectric element structure, wherein a first surface of the piezoelectric ceramic material and the first surface of the first reusable single layer substrate are in direct contact; depositing an electrode on a second surface of the at least one piezoelectric element structure; bonding the at least one piezoelectric element structure to a second substrate, the second substrate being conductive or having a conductive layer; removing the at least one first reusable single layer substrate from the at least one piezoelectric element structure; depositing a second side electrode on the first surface of the at least one piezoelectric element structure; and poling, by applying a DC voltage to the at least one piezoelectric element structure, to provide the at least one piezoelectric element structure with piezoelectric characteristics.
