An Effective Passive Micromixer Employing Herringbone Structure

Keywords: hydrophilic, hydrophobic, herringbonelike

Abstract:
This paper proposes a high efficient micro mixer, passively employing surface tension force as driving power and Herringbone structures as vortex generator for fluid mixing. The fluidic channel was designed without sidewall and confined with only the bottom hydrophilic and top hydrophobic surface for later-on mixing process among channels. Besides, in order to increase the mixing efficiency, herringbone-like structures are arranged on the bottom of the channel to enforce liquids to produce three-dimensional flow automatically. The fabrication has been completed successfully, and the testing result demonstrated 5 times higher mixing rate in 15mm mixing range. This device is anticipated to be batch-fabricated and applied to power-free mTAS or lab-on a-chip system in the future.
