Performance Characterization of a Traveling-Wave Electrohydrodynamic Micropump
Abstract
Microscale fluidic manipulation using traveling-wave, induction electrohydrodynamics is demonstrated. A three-phase traveling-wave device fabricated for the experiments provides a temporally and spatially varying electric field which helps induce ions in a fluid subject to a temperature gradient. These ions are moved as the traveling wave propagates, resulting in a drag force being exerted on the surrounding fluid. Repulsion-type electrohydrodynamic flow is visualized in a microchannel of depth 50 μm, and results are presented in terms of velocity measurements using particle image velocimetry.
