FLUID EJECTION USING MEMS COMPOSITE TRANSDUCER
A method of ejecting a drop of fluid includes providing a fluid ejector. The fluid ejector includes a substrate, a MEMS transducing member, a compliant membrane, walls, and a nozzle. The substrate includes a cavity and a fluidic feed. A first portion of the MEMS transducing member is anchored to the...

| description | A method of ejecting a drop of fluid includes providing a fluid ejector. The fluid ejector includes a substrate, a MEMS transducing member, a compliant membrane, walls, and a nozzle. The substrate includes a cavity and 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 being anchored to the substrate. 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. A quantity of fluid is supplied to the chamber through the fluidic feed. An electrical pulse is applied to the MEMS transducing member to eject a drop of fluid through the nozzle. |
