APPARATUSES AND METHODS FOR MODULATING FLUIDS USING ACOUSTICALLY OSCILLATING SOLID STRUCTURES

摘要

An acoustofluidic apparatus is provided that functions by the generation of microstreaming in fluid produced by the oscillation of oscillatory elements excited by an energy input such as acoustic energy. An acoustofluidic apparatus includes an oscillatory energy field generator in energetic contact with one or more oscillatory elements contained in a fluid passage. Oscillation of the oscillatory elements induces microstreaming in a fluid that can be used to mix laminar flows of differing fluids, as a micropump for the directional movement of fluid through a fluid passage, for the generation of waveforms in a fluid or plurality of fluids or for other purposes.
