Abstract
A micro-electromechanical fluid control device includes at least one flow guiding unit. The at least one flow guiding unit includes an inlet plate, a substrate, a resonance membrane, an actuating membrane and an outlet plate sequentially stacked. A first chamber is defined between the resonance membrane and the actuating membrane and a second chamber is defined between the actuating membrane and the outlet plate. While the piezoelectric membrane of the flow guiding unit drives the actuating membrane, a fluid is inhaled into the convergence chamber via the inlet of the inlet plate, transported into the first chamber via the central aperture of the resonance membrane, transported into the second chamber via a vacant space of the actuating membrane, and discharged out from the outlet of the outlet plate, so as to control the fluid to flow.
