Compact Modeling of MEMS Contact Current upon Pull-In

Røst H.I., Clark J.V., Pister K.S.J., Auburn University, US

This work-in-progress presents a parameterizable compact model of a microelectromechanical system (MEMS) beam element that includes mechanical contact and electrical current flow upon gap closure. Quasistatic electromechanical simulation analyses include the initial onset of pull-in [...]

Simulation Toolkit for Micro-Fluidic Pumps using Lumped Models

Litterst C., Streule W., Zengerle R., Koltay P., IMTEK, University of Freiburg, DE

Simulation of micro pumps is complicated by the interaction of various physical domains. The fluid structure interaction (FSI) essentially determines the dynamics of micro pumps and therefore has to be taken into account. Mesh based [...]

Simulation of a Micro Dispenser Using Lumped Models

Koltay P., Moosmann C., Litterst C., Streule W., Zengerle R., University of Freiburg, DE

In this paper the modelling of a micro dispenser by system simulations according to fluidic network theory is reported. The dispensing device under consideration (the so called “Nano-Jet” dispenser) is described in detail in [1]. [...]

Modelling Free Jet Ejection on a System Level – An approach for microfluidics

Koltay P., Moosmann C., Litterst C., Streule W., Birkenmeier B., Zengerle R., University of Freiburg, DE

Fast simulation of complex microfluidic systems requires consideration of network simulations based on lumped models as an alternative to standard computational fluid dynamic (CDF) simulations. In this paper we describe an analytical model of an [...]
