1. A microfluidics acoustic pump system, comprising:

  • a flow passage configured to carry a fluid from one location to another;

    a first wedge-shaped flow generator disposed within the flow passage and comprising two planar, nonparallel sides that converge together to form a first sharp edge;

    a second wedge-shaped flow generator disposed within the flow passage and comprising two planar, non-parallel sides jointed together at a second sharp edge; and

    a driving device configured to vibrate the flow passage to create a streaming fluid flow in a direction away from the sharp edges of the first and second flow generators through the flow passage, wherein the driving device is configured to vibrate the first flow generator and the second flow generator at a resonance frequency of the first flow generator and the second flow generator.
