Layout Verification by Extraction for Micro Total Analysis Systems

Baidya B., Mukherjee T., Carnegie Mellon University, US

The increasing complexity of MicroTotalAnalysis Systems is leading to a growing need for verification tools for such designs. Numerical simulation of such designs are slow, memory consuming and practically impossible for large designs. Schematic-based simulation [...]

Topology Trade-offs in the Synthesis of Chip-based Electrophoretic Separation Systems

Pfeiffer A.J., Mukherjee T., Hauan S., Carnegie Mellon University, US

Micro-scale electrophoretic separation systems provide a highly effective, versatile and inexpensive method for separating a wide variety of chemical components. Particularly useful applications include separation of biological molecules, chemical sensing, and mobile drub delivery systems. [...]

Numerical Simulation of Microfluidic Flow Using a Combination of Micro and Macro Computational Techniques: Scaling Issues

Mautner T., SPAWAR Systems Center San Diego, US

Recent literature has demonstrated the possibilities of using configurable surfaces to enhance the flow of fluids in MEMS devices. Not only are surface properties important in fluid delivery, the inherent problems of mixing by diffusion [...]

Numerical Simulation of Field Amplified Sample Stacking in Microfluidic System

Feng J.J., Krishnamoorthy S., Sundaram S., Bhardwaj R., Santiago J.G., CFD Research Corporation, US

In this paper we developed a numerical simulation method that solves the transport phenomenon associated with sample stacking in microchip-based separation system. The model is based on thin double layer approximation where the electrostatic force [...]

Simulation and Optimization of Colloidal Micropumps

Liu D., Maxey M., Karniadakis G., Brown University, US

A fast algorithm for particulate microflows has been used to simulate the 3D micro-colloidal pumps tested in the experiments conducted by Terray et al. The Force-Coupling Method and a penalty method were implemented in a [...]

Modular Silicon Micropump

Johnson A.D., Martynov V., Gupta V., Menchaca L., TiNi Alloy Company, US

A new micropump mechanism has been created that consists of two silicon/silicon oxide dies with vias and dome-shaped membranes. The membranes are bonded face-to-face to form variable-volume domed liquid chambers. The membranes increase and decrease [...]
