We present a novel μm-resolution particle-image velocimetry setup capable of automated full-chip measurements of microchannel acoustophoresis. Our system allows for fast collection of a sufficient amount of data enabling reliable determination of the influence from the forces from acoustic radiation and acoustic streaming acting simultaneously on microbead suspensions in a microfluidic system.
From a series of acoustophoretic focusing experiments on 5 μm, 3 μm, and 2 μm polystyrene (PS) microbead suspensions, we quantify the particle velocity induced by the acoustic radiation force and show that it scales with the expected microbead radius to the power two.
