FLUID EJECTION DEVICE

摘要

A fluid ejection device includes a substrate (120; 120') having a fluid channel (160) including a fluid inlet (162) and a fluid outlet (168), a flexible membrane (130) supported by the substrate and extended a length of the fluid channel, an actuator (140) provided on the flexible membrane, and a constriction (165) provided within the fluid channel between the fluid inlet and the fluid outlet, such that the actuator is adapted to deflect the flexible membrane relative to the fluid channel, and the constriction supports the flexible membrane between the fluid inlet and the fluid outlet.
