ABSTRACT:
This invention relates to a micromachined fluid ejector array having a fluid reservoir bounded at one side by an elastic membrane having scalable arrays of orifices arranged between concentric piezoelectric transducers, and at another side by a top cover supported by surrounding walls. By actuating neighboring concentric piezoelectric transducers, the scalable array of orifices arranged between the actuated neighboring concentric piezoelectric transducers deflect to eject fluid droplets. Also disclosed is a micromachined fluid ejector array having a fluid reservoir bounded at one side by an elastic membrane having scalable arrays of orifices arranged between concentric piezoelectric transducers, and at another side by a top cover supported by surrounding walls. A piezoelectric layer is bonded on top of the top cover. By actuating the piezoelectric layer bonded on top of the top cover, the scalable arrays of orifices arranged between the neighboring concentric piezoelectric transducers deflect in phase to eject fluid droplets.
