Volume 10: Micro and Nano Systems, 2010
We have developed a novel fabrication technique for a passive, continuous flow micromixer with laminar flow. The device is made by welding thin thermoplastic sheets using a simple manufacturing procedure which reduces the total cost of the device, and enables frequent changes to the design as necessary. Two types of mixers were made, one with obstacles

Volume 9: Micro- and Nano-Systems Engineering and Packaging, Parts A and B, 2012
This paper presents the fabrication of a 3D microchannel whose sidewalls and bottom surface are patterned with ratchets using a modified 3D molding process. In the modified 3D molding process the surface of poly(methyl methacrylate) (PMMA) is first patterned using a brass mold having ratchet structures.

Barrier Embedded Chaotic Micromixer
The Sixteenth Annual International Conference on Micro Electro Mechanical Systems, 2003. MEMS-03 Kyoto. IEEE, 2002In this paper, we present a new chaotic passive micromixer named barrier embedded micromixer (BEM), with mixing visualization experimental results. Chaotic mixing in the microchannel has been successfully achieved by introducing periodic barriers on one microchannel wall which cause periodic perturbation in the velocity field of the helical flow.

A novel electrokinetic micromixer
Sensors and Actuators A: Physical, 2004A novel microfluidic mixer based on the modulation of /spl zeta/-potential is proposed and demonstrated successfully. In contrast to previous micromixer work from other groups, this micromixer does not need complex three-dimensional serpentine microstructure or external pumps to generate chaotic advection pulsatile flow.

Bubble-induced acoustic micromixing
Lab on a Chip, 2002A mixing technique based on the principle of bubble-induced acoustic microstreaming was developed. The mixer consists of a piezoelectric disk that is attached to a reaction chamber, which is designed in such a way that a set of air bubbles with desirable size is trapped in the solution.

Science, 2004
Microfluidic devices are becoming more common and essential to a range of technologies. In their Perspective, [Ottino and Wiggins][1] discuss recent results in an important aspect of this field: micromixing. In contrast to everyday fluids, fluids flowing in small structures are dominated by viscous effects. This in turn makes mixing difficult.

Micromixers to produce cosmetic emulsions
International Journal of Cosmetic Science, 2003SynopsisIn the cosmetics industry, emulsions play a key‐role in active solubilization and texture/efficacy optimization. However, depending on their physico‐chemical properties, the active ingredients are often more stable in a single phase: for example, Vitamin A is more stable in an oily phase than in a water phase.We have developed a special mixing ...
