摘要： An electrostatic liquid-ejection actuation mechanism includes a membrane, a frame, and one or more deformable beams. The frame has two sides and a number of cross members that are non-parallel to the two sides. The two sides and the cross members define one or more areas individually corresponding to one or more liquid chambers. The deformable beams are disposed between the membrane and the frame. The deformable beams individually correspond to the liquid chambers, and define a number of slits. Each slit is adjacent to one of the two sides of the frame. The deformable beams have a width that is less than a width of the liquid chambers, due at least to the slits.

摘要： A printhead architecture includes a die having a chamber formed therein. The chamber is at least partially defined by opposed walls. An actuator is positioned over the chamber, and includes a first electrode, a piezoceramic layer in contact with the first electrode, and a second electrode in contact with the piezoceramic layer and discrete from the first electrode. A membrane, which is to be activated by the actuator, overlies the chamber and walls. A first trace, positioned adjacent to but discrete from the actuator, overlaps a portion of the chamber and a portion of one of the opposed walls. A second trace, positioned adjacent to but discrete from the actuator, overlaps another portion of the chamber and a portion of another one of the opposed walls. Each of the first and second traces has a respective width and thickness sufficient to provide additional stiffness to the membrane.

The first and the second electrodes are embedded within the thin film sheet. The thin film sheet is polarized in a direction at least substantially perpendicular to a surface of the thin film sheet. The thin film sheet is to physically deform in a shear mode due to polarization of the thin film sheet at least substantially perpendicular to the surface of the thin film sheet, responsive to an electric field induced within the thin film sheet at least substantially parallel to the sheet via application of a voltage across the first and the second electrodes.

摘要： A piezoelectric inkjet die stack includes a printhead substrate die, a pedestal seated on the printhead substrate die, a fluidics die seated atop the pedestal, and integrated circuit (IC) dies seated on the printhead substrate die. The IC dies may be positioned substantially but not completely beneath the fluidics die and positioned on either side of the pedestal such that air gaps exist between a top surface of each IC die and a bottom surface of the fluidics die and between each IC die and the pedestal. The pedestal may include ink flow channels to allow ink flow between the fluidics die and the printhead substrate. A plurality of stand-offs may be implemented to help support the fluidics die above the IC dies.
