The present invention includes an apparatus and corresponding method for fluid flow control in microfluidic applications. A microchamber, filled with a fluid, is in fluid contact with a flexible plate. A transducer is acoustically coupled to the flexible plate. A function generator outputs a signal to excite the transducer, which in turn induces drumhead vibration of the flexible plate, creating a flow pattern within the fluid filled microchamber.
