Lead-free piezo printhead using thinned bulk material
An apparatus for a lead-free piezoelectric ink-jet printhead is disclosed. Piezoelectric printheads, while more expensive are favored because they use a wider variety of inks. The piezoelectric printhead includes a diaphragm, a plurality of piezoelectric actuators comprising a lead-free piezoelectric material, at least one nozzle, at least one ink chamber, a top electrode, and a drive circuit. The deflection of the diaphragm on the body chamber contributes to a pressure pulse that is used to eject a drop of liquid from the nozzle. According to an exemplary embodiment, a lead-free piezoelectric printhead operated at smaller thicknesses and significantly higher electric fields is disclosed, along with methods of making such printheads.
