  • Lateral cavity acoustic transducer based microfluidic switch
    Patent number: 9517465
    Abstract: A microfluidic switching device that includes an upstream microfluidic channel configured to contain a liquid having particles therein and a plurality of outlet channels coupled to the upstream microfluidic channel at a junction. A dead-end side channel or LCAT is oriented generally perpendicular to the upstream microfluidic channel and coupled to the upstream microfluidic channel at the junction, the dead-end side channel having a gas contained therein. The device includes a transducer configured to apply an external source of acoustic energy. Actuation of the transducer effectuates symmetrical oscillation of a gas/liquid boundary at the junction. Preferably, the junction comprises a bifurcation with two outlets. Further, the LCAT has a leading edge and a trailing edge and wherein the trailing edge of the LCAT is substantially aligned with the bifurcation.
