Abstract:
A piezoelectric printhead and related methods provide a first metallic electrode and a second metallic electrode deposited over a top surface and a bottom surface, respectively, of a piezoceramic plate. The second electrode is segmented into a plurality of electrode segments. A diaphragm is positioned over a plurality of pressure chambers, where the diaphragm includes a conductor positioned over each chamber. The piezoceramic plate is attached to the diaphragm such that each conductor on the diaphragm faces multiple electrode segments.
