Ac Electro-osmotic Micromixer Using a Face-to-face, Asymmetric Pair of Planar Electrodes

چکیده
T This paper reports the mixing performance of an AC electroosmotic micromixer based on the three-dimensional extensional flow generated by a face-to-face, asymmetric pair of planar electrodes. This work represents the first successful use of such an asymmetric electrode pair in an AC electroosmotic micromixer. Due to the highly 3dimentional flow pattern generated by the face-to-face electrode pair, the mixing enhancement factor ( mixing time by diffusion / mixing time by the micromixer) of the reported micromixer is 10 times larger than those using co-planar electrode pairs, and the mixing performance is uniform across the entire height of the fluid cavity.

Pumping of liquids with ac voltages applied to asymmetric pairs of microelectrodes.
The net flow of electrolyte induced by an ac electric potential applied to an array of asymmetric pairs of microelectrodes has recently been reported. The interaction between the oscillating electric field and the oscillating induced charge at the diffuse double layer on the electrodes results in a steady electro-osmotic velocity distribution on top of the electrodes. This slip velocity distrib...
متن کاملDesign and fabrication of an ac-electro-osmosis micropump with 3D high-aspect-ratio electrodes using only SU-8
Lab-on-a-chip devices require integrated pumping and fluid control in microchannels. A recently developed mechanism that can produce fluid flow is an integrated ac-electro-osmosis micropump. However, like most electrokinetic pumps, ac-electro-osmotic pumps are incapable of handling backpressure as the pumping force mechanism acts on the surface of the fluid rather than the bulk. This paper pres...
متن کاملDesign principle for improved three-dimensional ac electro-osmotic pumps.
Three-dimensional (3D) ac electro-osmotic (ACEO) pumps have recently been developed that are much faster and more robust than previous planar designs. The basic idea is to create a "fluid conveyor belt" by placing opposing ACEO slip velocities at different heights. Current designs involve electrodes with electroplated steps, whose heights have been optimized in simulations and experiments. Here...
متن کاملThe effect of step height on the performance of three-dimensional ac electro-osmotic microfluidic pumps.
Recent numerical and experimental studies have investigated the increase in efficiency of microfluidic ac electro-osmotic pumps by introducing nonplanar geometries with raised steps on the electrodes. In this study, we analyze the effect of the step height on ac electro-osmotic pump performance. AC electro-osmotic pumps with three-dimensional electroplated steps are fabricated on glass substrat...
متن کاملTheoretical prediction of fast 3D AC electro-osmotic pumps.
AC electro-osmotic (ACEO) pumps in microfluidics currently involve planar electrode arrays, but recent work on the underlying phenomenon of induced-charge electro-osmosis (ICEO) suggests that three-dimensional (3D) geometries may be exploited to achieve faster flows. In this paper, we present some new design principles for periodic 3D ACEO pumps, such as the "fluid conveyor belt" of ICEO flow o...
