This paper studies the application of laminate magnetoelectric (ME) material in displacement sensor. We studied the L-L block composite thanks to designed structure by coupling displacement signal with the displacement potential of ME composite. A nonlinear approximation is adapted to modeling magnetostrictive phase and implemented in COMSOL Multiphysics® software. The simulation results ...

Powerful automation and optimization methods for Material- and Process analysis with COMSOL Multiphysics and Matlab
SGL Group, Technology & Innovation, Meitingen, Germany
Thomas Frommelt received his PhD in physics in 2007 from the University of Augsburg for experimental work and simulation analysis on acoustically driven microfluidic mixing. In 2008, he joined the SGL Group and introduced COMSOL Multiphysics as the tool for flexible equation based modelling. Since then, he has focused on carbon material and process simulation employing methods of optimization ...

Operation of a modified type microthrottle (MT) pump is analyzed by numerical simulation. Conventional MT pumps have disk type piezoelectric membranes while the analyzed type has a membrane of a rectangular shape. This could be advantageous in case the pump is stacked into an array for parallel pumping. A complete electro–fluid–solid mechanics coupling model for numerical simulation of strip ...

Introduction: Accurate fluid temperature control in microfluidic channels is a requirement for many lab-on-chip and micro-reactors.Thin films resistive metal heaters have proven to be the best choice for localizing heating applications with integrated microfluidic systems. A thin platinum layer has been chosen as the metal used to realize the meander because of its positive and linear ...

The primary function of the vestibular system is to provide the brain with information about the body\'s motion and orientation. The absence of this information causes blurred vision and spatial disorientation, vertigo, dizziness, imbalance, nausea, vomiting, and other symptoms often characterize dysfunction of the vestibular system. Our aim is to design vestibular prosthesis using COMSOL ...

Design of SAW devices needs the accurate study of the scattering fields, arising from the interaction of SAW with topographic irregularities. To solve this problem FE methods very perspective, because with its help one can take into account the actual geometry of the electrodes and reflectors. This work describes results of original time domain calculation of 2D SAW scattering fields in delay ...

Capacitor Discharge Sintering (CDS) is an ultrafast Electric Current Assisted Sintering method (u-ECAS) suited for electrically conductive powders. It is characterized by relatively short processing times (milliseconds range) and much lower sintering temperatures than the melting point of the powders. However, the CDS basic phenomena are not fully understood yet neither at the macroscale nor at ...

Modeling of 3D AC electro-osmotic pumps is relevant to the creation of portable or implantable lab-on-a-chip devices for mm/s tunable fluid flows attainable with battery scale voltages. In this analysis using COMSOL Multiphysics we investigate the modeling challenges of computationally calculating systems of fluid flow phenomena governed by AC Electroosmosis in the micro and nano scale regimes.
