Analysis of Electrically Induced Swirling Flow of Isotonic Saline in a Mixing Microchannel

Micro Total Analysis Systems: Latest Achievements

“…New and improved methods are continually being developed: Low-voltage traveling electric wave electrohydrodynamic pumping using high frequencies (MHz) can be combined with temperature fields to manipulate the dielectric profile and therefore the velocity distribution . Alternatively, high-frequency ac (20 V pp , 5 MHz) methods have been used to locally induce buoyancy to drive fluid within a vertical circuit at rates as high as 110 nL/s . Using top and bottom fluidic interconnection as well as top and bottom driving electrodes, electroosmotic flows can be massively parallelized into an array of approximately half a million microchannels .…”
