Reconfigurable Microfluidic System Architecture Based on Two-Dimensional Electrowetting Arrays

Ding J., Chakrabarty K., Fair R.B., Duke University, US

We present an architectural design and optimization methodology for performing biochemical reactions using two-dimensional electrowetting arrays. We define a set of basic microfluidic operations and leverage electronic design automation principles for system partitioning, resource allocation, [...]

A Combined DSMC/Meshless Technique for Multiscale Analysis of Microfluidic Filters

Aktas O., Aluru N.R., University of Illinois at Urbana-Champaign, US

A multiscale method that couples a meshless Stokes solver and a DSMC simulator is reported. The method is based on overlapped Schwarz alternating method with Dirichlet-Dirichlet type boundary conditions for domain decomposition and meshless interpolation

Modelling of Integrated Peltier Elements

Wijngaards D.D.L., Cretu E., Kong S.H., Wolffenbuttel R.F., DIMES ITS/Et, NL

On-chip integration of Peltier devices creates a number of additional parasitics, compared to conventional Peltier devices. The most important are thermal conduction through the supporting membrane and contact resistance. Analytical analysis shows that each parasitic [...]

Simulation and Experimental Verification of Micro Polymerase Chain Reaction Chip

Lin Y-C., Yang C-C., Hwang M-Y., Chang Y-T., Cheng Kung University, TW

This study used finite element analysis to simulate the temperature characteristics of a micro polymerase chain reaction (PCR) chip. The micro-PCR chip was fabricated on a silicon wafer and Pyrex glass using photolithography, wet etching, [...]

Simulation of Heat-Transfer Enhancement Effects in Microreactors

Hardt S., Ehrfeld W., Hessel V., Vanden Bussche K.M., Institut für Mikrotechnik Mainz GmbH, DE

Sate-of-the-art microstructuring techniques allow to model the interface for heat and mass transfer in miniaturized reactions systems on a micrometer scale. In this context, two different approaches for heat transfer enhancement are presented. The ideas [...]

Thermal Management of Micro-Hotplates using MEMCAD as Simulation Tool

Briand D., Grétillat M.-A., van der Schoot B., de Rooij N.F., Institute of Microtechnology, CH

In this paper we report on the electrothermal simulations performed in the aim of optimising the power consumption and the temperature distribution of micro-hotplates for gas sensing applications. The micro-hotplate designs were optimised using the [...]

Numerical Simulation of Pulse-Width-Modulated Micropumps with Diffuser/Nozzle Elements

Nguyen N-T., Huang X., Nanyang Technological University, SG

This paper presents the numerical simulation of a new control method for dynamic micropumps with diffuser/nozzle elements: the pulse-width-modulation (PWM) of the drive signal. A piezo disk with a square wave signal actuates the pump, [...]

Dynamic Analysis of an Electrostatic Micropump

Jiang T.Y., Ng T.Y., Lam K.Y., National University of Singapore, SG

In this paper, a micropump actuated by electrostatic force is dynamically analysed. Mathematical model is established to evaluate the dynamic response of the micropump. Electro-mechanical coupling effect is considered in evaluating the electrostatic force applied [...]
