In this paper, the gross electrical characterization of biological cells on porous substrate using COMSOL Multiphysics is analyzed. Dynamic electrical characterization during cell growth is required as non invasive and label free technique to understand the growth kinetics of cells. It is observed from COMSOL simulation that the percentage change in current density is greater in porous substrat...

Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior in the glass transition regime. COMSOL Multiphysics software 4.3b can simulate the stress relaxation with the WLF (WilliamsLandel-Ferry) shift function, but no structural relaxation. In this study we developed a framew...

In this paper, we have addressed the design and simulation results of an electrothermally driven micromirror that is capable of producing in-plane as well as out-ofplane displacements. The coupled multiphysics simulation and study of the electrical, thermal and most importantly the mechanical behavior of the mirror system is done using COMSOL Multiphysics. The device has an in-plane displacemen...

This paper presents the simulation of the dual electromagnet Active Magnetic Levitation System realized in the COMSOL Multiphysics software. The mixed mode of Partial Differential and Ordinary Differential Equations is used to realize the levitated object motion. Two control scenarios are given as illustrative example of the working model.

We present a Finite Element Method simulation procedure that allows rapid development of prototype devices comprising novel self-referenced interference SPR (surface plasmon resonance) biosensing microstructures. The procedure takes advantage of commercial Comsol Multiphysics and Matlab software and their bi-directional link.

In this paper, we have design MEMS module based on thermal expansion using COMSOL Multiphysics. This device thermally expands when it is subjected to temperature. Beryllium copper alloy is used as material for this device. The expansion is measured in-terms of displacement.

This theoretical study describes the optical multilayer structure models leading to investigate Surface Plasmon Polariton (SPP) to an extern applied magnetic field at visible wavelenght using a 3D-FEM based on Comsol Multiphysics software. The layered structures include the amorphous silicon c-Si octahedral nanocrystals on the interface SiO2/dielectric were investigated to enhance the SPP inten...

The paper presents an analytical method for the determination of the magnetic force produced by a mini – actuator with permanent magnets. The results are compared with those obtained by performing a numerical field analysis with COMSOL Multiphysics, showing a very good agreement. The study reveals that the actuator has two equilibrium points, one of which is stable and the other one unstable.

Organogenesis is a tightly regulated process that has been studied experimentally for decades. We are developing mechanistic models for the morphogenesis of limbs, lungs, and kidneys with a view to integrate available knowledge and to better understand the underlying regulatory logic. In our previous paper on simulating organogenesis in COMSOL (German et al COMSOL Conf Procedings 2011) we discu...
