Characterization and modeling of a bulk acoustic wave particle focusing device

In this paper, we discuss our work in the modeling and characterization of an acoustic-microfluidic focusing device that uses standing bulk acoustic waves to focus particles under flow. Modeling was done using Comsol Multiphysics
^reg
(Comsol, Los Angeles, CA), a multiphysics FEM tool, and the performance of the device was assessed through coefficient of variance (CV) measurements using a confocal microscope.
