Abstract
Mixing of microfluidic flows is difficult due to the fact that microfluid is generally laminar flow and turbulence is not enough. To improve the mixing of microfluid, passive or active microfluidic mixers are developed. Active micromixers need external energy input, but generally result in better mixing outcome compared to passive micromixers. In this poster, an active rotary microfluidic mixer with four rotary blades is designed. It has three inlets and one outlet. The four rotary blades introduce turbulence of the microfluid to help improve the mixing. The four rotary blades are arranged to form a fully differential structure. They can be activated to rotate clockwise, counter-clockwise or with a combination of both. The shape of the micromixer is custom-designed to reduce the dead angle compared to traditional cylinder mixer.
