Patent ID: 8434855

Claim:
A fluid ejector comprising: a substrate, first portions of the substrate defining an outer boundary of a cavity and second portions of the substrate defining a fluidic feed; a MEMS transducing member, a first portion of the MEMS transducing member being anchored to the substrate, a second portion of the MEMS transducing member extending over at least a portion of the cavity, the second portion of the MEMS transducing member being free to move relative to the cavity; a compliant membrane positioned in contact with the MEMS transducing member, a first portion of the compliant membrane covering the MEMS transducing member, and a second portion of the compliant membrane being anchored to the substrate; partitioning walls defining a chamber that is fluidically connected to the fluidic feed, wherein at least the second portion of the MEMS transducing member is enclosed within the chamber; and a nozzle disposed proximate to the second portion of the MEMS transducing member and distal to the fluidic feed, wherein the compliant membrane does not extend over the fluidic feed.
