Abstract

Particle image velocimetry (PIV) provides a non-invasive, microfluidics compatible approach for characterization of flow fields in μTAS systems. This paper describes the application of confocal microscopy to improve the spatial resolution of PIV thereby enabling measurement of fine detail in flow fields by using the superior resolution and optical sectioning ability of confocal imaging. The three-dimensional velocity field present in a microchamber driven by a piezoelectric diaphragm was measured using this approach. Experimental results confirm the role of acoustic streaming in the generation of the velocity profiles.
