    Abstract: An integrated varactor and piezoelectric device (130) for an acoustic ink jet ejector (100) includes a silicon substrate (102) having a first surface, the silicon substrate forming a first electrode, an epitaxial layer (132) formed over the first surface of the silicon substrate, a silicon dioxide layer (134) formed over the epitaxial layer, a second electrode (104) formed over the silicon dioxide, a piezoelectric layer (106) formed over the second electrode, a third electrode (32) formed over the piezoelectric layer and an acoustic lens (108) formed over a second surface of the silicon substrate. The acoustic lens is aligned with the center of the piezoelectric layer generally along an axis perpendicular to the first and second surfaces of the silicon substrate.

    Abstract: An acoustic ink printhead with an integrated liquid level control layer has a spacer layer (27) fixed to a substrate (20). Apertures (28A, 28B) are created in the spacer layer, which is then used as a mask, to define acoustic lenses (36A) and ink supply channels (36B) in the substrate. The apertures in the spacer layer define self-aligned acoustic lenses and form cavities to hold the ink reservoirs for each ejector. The thickness of the spacer layer is set so that acoustic waves from the acoustic lens below are focused at the free surface of the ink which maintains its level at the top of the spacer layer by capillary action.

    Abstract: A multiple-ejector system for printing arrays of biofluids include a tooling plate having a plurality of sets of tooling pins extending outward from the surface of the tooling plate. A printed circuit board is provided having pairs of power connection pins and ground return pins extending from a surface of the circuit board. A plurality of biofluid drop ejection units are provided and include alignment grooves and at least a transducer. Each of the plurality of biofluid drop ejection units are connected to a corresponding one of a set of tooling pins by connection of the tooling pins and alignment grooves. The power connection pins of the pairs are in operational connection with respective transducers and the ground return connection pins of the pairs are in operational connection with a body portion of the drop ejection units. The different drop ejection units will contain different biofluids which are to be emitted onto a substrate. Verification of drop ejection units containing biofluids, may be obtained in one embodiment through the use of an optical scanner. Detection of drops at defined locations provides a verification that validates a properly formed spot is present on a substrate, and is in the correct position.

    Abstract: Low acoustic solid wave attenuation structures are formed with an electroformed nickel mold, and are incorporated within acoustic ink emitters, between the focusing lens and surface of an ink layer. The structures have characteristics of low attenuation of acoustic waves to increase the efficiency of acoustic wave transmission within the acoustic ink emitter. Using the described structures, acoustic ink printers can accurately emit materials having high viscosity, including hot melt inks.
