    摘要： A fluid ejector includes a substrate, a MEMS transducing member, a compliant membrane, walls, and a nozzle. First portions of the substrate define an outer boundary of a cavity. Second portions of the substrate define a fluidic feed. A first portion of the MEMS transducing member is anchored to the substrate. A second portion of the MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. The compliant membrane is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member. A second portion of the compliant membrane is anchored to the substrate. Partitioning walls define a chamber that is fluidically connected to the fluidic feed. At least the second portion of the MEMS transducing member is enclosed within the chamber. The nozzle is disposed proximate to the second portion of the MEMS transducing member and distal to the fluidic feed.

    摘要： A liquid ejector includes a substrate, a heating element, a dielectric material layer, and a chamber. The substrate includes a first surface. The heating element is located over the first surface of the substrate such that a cavity exists between the heating element and the first surface of the substrate. The dielectric material layer is located between the heating element and the cavity such that the cavity is laterally bounded by the dielectric material layer. The chamber, including a nozzle, is located over the heating element. The chamber is shaped to receive a liquid with the cavity being isolated from the liquid.

    摘要： A method of continuously ejecting liquid includes providing a liquid ejection system that includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate includes a MEMS transducing member that extends over at least a portion of the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. The compliant membrane includes an orifice. Liquid is provided under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate by a liquid supply. A drop of liquid is caused to break off from the liquid jet by selectively actuating the MEMS transducing member which causes a portion of the compliant membrane to be displaced relative to the liquid chamber.
