This talk demonstrates the success in teaching chemical engineering undergraduates to use COMSOL Multiphysics (FEMLAB) to solve realistic problems in a project format. Undergraduates have been creative and solved problems much more difficult than those in their textbooks, thus gaining a deeper understanding of transport processes. Illustrations are also given how they check to see they’ve ...

In this paper, a methodology to simulate the electric behavior of spiral inductances is presented and discussed. All the methodology is built with the COMSOL software used with the Matlab scripting interface and then allows performing fully parameterized simulations. The program architecture is explained and is used to simulate two applications. The first calculates the voltage induced by an ...

This paper gives an overview of modelling microsensors on geometry and system level. The focus will be on the generation of the multiphysics reduced order system model and the coupling with package and ASIC models. The method is based on modal superposition. This means all the details of the sensor can be considered in a finite element model. The mechanical mode shapes of this model form the ...

We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector. We have successfully performed some experimental evaluations of the detection principle and are in the stage of optimization of several parts of the system. As shown ...

In this study, a detailed finite element model coupling the motion dynamics and electromagnetics of a diaphragm based MEMS vibration energy harvester is presented. The energy harvester converts low frequency vibrations to high frequency response by magnetic actuation of a diaphragm carrying coils. AC/DC, Solid Mechanics and Moving Mesh (ALE) modules are coupled together in one 3-D model to ...

The aim of this work was to simulate the electro-thermal behavior of a micro-hotplate used as a gas sensor, in order to compare the obtained results with a real structure. The structure has been designed in 3D and a stationary and a temporal study has been realized.

Electric Field Assisted Capillarity (EFAC) is a novel technique for the fabrication of hollow polymer microstructures. It has advantages over current methods as it is a single step process. Hollow microstructures have many uses in industry from microchannels and microcapsules in BioMEMS to fibre-optical waveguides. It makes use of the dielectric properties of polymers combined with a heavily ...

This paper deals with experimentation, modelling, simulation and optimisation of a Moisture Management Tester (MMT) which is used to determine the liquid spreading and transfer rates of a fabric. A 3D model was developed and implemented within FEMLAB. It consists of partial differential equations describing the mass balance of water adsorbed on the fibres and water moving in the free volume ...

We have developed a novel, multilayered microfluidic chamber that enables the realtime quantitative study of chemotaxis on virtually all types of motile cells. In this paper, we present a FEMLAB modeling study of the 3D chamber design, including a consideration of each device iteration that successively led to the eventual design. The final chamber design is able to create and maintain an ...

In this work, a system for magnetic and hydrodynamic manipulation of magnetic beads is modelled. A geometry is introduced to assure a good separation behaviour with respect to the magnetic moment of the particles. Different separation mechanisms will be discussed and an estimation of the minimal difference of separable magnetic moments will be given. Further it will be shown, that the ...
