Abstract
We have observed that microchannel liquid flows subjected to sinusoidally alternating electric fields exhibit, under certain electric field strengths and geometries, a flow instability capable of rapidly stirring micro- and nanoliter volume solutions. We present the design, fabrication, and characterization of two micromixers: a prototype device Micromixer I and a more robust, 2nd generation device Micromixer II that utilize an electrokinetically induced instability as the stirring mechanism and may be easily integrated into many microfluidic chip designs.
