Abstract

In this paper steady electro-osmotic flow (EOF) in cross-straight channel is measured by micro particle image velocimetry (micro-PIV). Micro channels with two elementary configurations, a straight channel and a cross-straight channel, are fabricated by wet chemical etching process on glass. The uniform Zeta potential is obtained form the ratio of averaged velocities of EOF in the straight channel under each external applied electric field, which is used in numerical simulation. The experiment shows that the flow patterns in cross-straight channel are controlled by different patterns of applied electric field, which directly make controllable the flux ratio of separated fluids.
