ABSTRACT:
A micro-electromechanical nozzle assembly includes a substrate that defines an ink chamber and an ink ejection port in fluid communication with the ink chamber on an ejection side of the substrate. A control circuitry layer is positioned on an ink ingress side of the substrate. An arcuate thermal actuator is fast with the control circuitry layer in a cantilever manner to be interposed between an ink reservoir and the ink chamber. The actuator is configured to straighten responsive to receipt of an electrical signal from the control circuitry layer so that ink within the ink chamber is ejected through the aperture.
