Abstract
A microfluidics acoustic pump system includes a flow passage configured to carry a fluid from one location to another, a selectively vibrating flow generator having a sharp edge, and a driving device configured to vibrate one of the flow generator and the flow passage to create a streaming fluid flow in a direction away from the sharp edge through the flow passage.
Claims24
A microfluidics acoustic pump system, comprising:
- a flow passage configured to carry a fluid from one location to another;
- a selectively vibrating flow generator having a sharp edge;
- and
- a driving device configured to vibrate one of the flow generator and the flow passage to create a streaming fluid flow in a direction away from the sharp edge through the flow passage.

A microfluidics acoustic pump system, comprising:
- a flow passage configured to carry a fluid from one location to another;
- a first flow generator disposed within the flow passage and comprising a sharp edge;
- a second flow generator disposed within the flow passage and comprising a sharp edge;
- and
- a driving device configured to vibrate one of a) the first and second flow generators and b) 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 fluid passage.

A method comprising:
- providing a flow generator in a flow passage filled with fluid, the flow generator having a sharp edge defined by two nonparallel surfaces forming an angle, the nonparallel surfaces being symmetrically disposed about an axis aligned with an axis of the flow path;
- and
- vibrating the flow generator with a driving device to vibrate the sharp edge of the flow generator to create fluid flow through the flow passage.
A microfluidics chip, comprising:
- a plurality of flow passages configured to carry a fluid from one location to another;
- a plurality of selectively vibrating flow generators having a sharp edge, at least one of the plurality of selectively vibrating flow generators being disposed in each of the plurality of flow passages, the plurality of selectively vibrating flow generators having different resonance frequencies;
- and
- a driving device configured to selectively induce vibrations at the different resonance frequencies of the plurality of flow generators in a manner that permits selective activation of each of the plurality of flow generators by controlling resonant alternating current to the driving device.
