ABSTRACT:
A micro-electromechanical device includes a substrate. A drive circuitry layer is positioned on the substrate. A nozzle chamber wall and a roof wall are positioned on the substrate to define a nozzle chamber above the substrate and a fluid ejection port in the roof wall. A substantially planar deformable fluid ejecting member is interposed between the substrate and the roof wall and is configured to deform cyclically under action of a pulsed electromagnetic field. The drive circuitry is configured to generate said pulsed electromagnetic field so that the fluid ejecting member acts on fluid to eject fluid from the fluid ejection port.
