    摘要： A printing device for jetting a liquid includes a flow path body having a plurality of jetting flow paths, a liquid in the plurality of jetting flow paths, a piezoelectric actuator associated with each jetting flow path, a feed substrate having a plurality of fluid inlets, and a driver configured to apply a voltage pulse to the piezoelectric actuator. The first jetting flow path is adjacent to the second jetting flow path and a fluidic travel distance from the piezoelectric actuator of the first jetting flow path to a nozzle of the second jetting flow path is greater than a speed of sound in the liquid times the break off time of a droplet of the fluid from the nozzle.

    摘要： Microelectromechanical systems with structures having piezoelectric actuators are described. The structures each have a body that supports piezoelectric islands. The piezoelectric islands have a first surface and a second opposite surface. The piezoelectric islands can be formed, in part, by forming cuts into a thick layer of piezoelectric material, attaching the cut piezoelectric layer to a body having etched features and grinding the piezoelectric layer to a thickness that is less than the depths of the cuts. Conductive material can be formed on the piezoelectric layer to form electrodes.

    摘要： A fluid ejector having an inner surface, an outer surface, and an orifice that allows fluid in contact with the inner surface to be ejected. The fluid ejector has a non-wetting monolayer covering at least a portion of the outer surface of the fluid ejector and surrounding an orifice in the fluid ejector. Fabrication of the non-wetting monolayer can include removing a non-wetting monolayer from a second region of a fluid ejector while leaving the non-wetting monolayer on a first region surrounding an orifice in the fluid ejector, or protecting a second region of a fluid ejector from having a non-wetting monolayer formed thereon, wherein the second region does not include a first region surrounding the orifice in the fluid ejector.

    摘要： A method and apparatus for bonding on a silicon substrate are disclosed. An apparatus includes a membrane having a lower membrane surface and an upper membrane surface, a transducer having a transducer surface substantially parallel to the upper membrane surface, and an adhesive connecting the membrane to the transducer surface. In some implementations, the lower membrane surface is substantially contiguous and the upper membrane surface protrudes therefrom. In some other implementations, the upper membrane surface is substantially contiguous and the lower membrane surface is recessed therein.
