A Novel In-Plane Passive Micromixer Using Coanda Effect

In this paper, an innovative in-plane passive micromixer using the “Coanda effect” has been designed, simulated, fabricated and successfully characterized. Simulation and experimental results of the developed novel micromixer have shown excellent mixing performances over a wide range of flow rate from 1 µl/min to 100 µl/min. The micromixer realized in this work has achieved even better mixing performance at a higher flow rate of 100 µl/min. Due to a simple in-plane structure of the novel micromixer, the mixer can be easily fabricated and integrated with total microfluidic systems.
