A Multiphysics Approach to the Modeling of Biological Prosthetic Heart Valves

A. Avanzini[1], D. Battini[1], M. Berardi[1]
[1]Università degli Studi di Brescia, Brescia, Italy

The complex behavior of biological prosthetic heart valves was simulated. A multiphysics computational approach was adopted using different modules of COMSOL Multiphysics: the LiveLink(TM) interface was used to exchange the valve geometry with CAD, Structural Mechanics Module to set ... Read More

Modeling of Silicon Piezoresistive Pressure Sensor: Application to Prevent Some Diabetes Complications

F. Kerrour[1], A. Beddiaf[1], M. Benabbas-Marir[1]
[1]MODerNa Laboratory, University Mentouri, Constantine, Algeria

Several analytical solutions describing the mechanical behavior of a silicon micro membrane deflection, perfectly embedded and subjected to a uniform and constant pressure have been proposed. The obtained results are compared with those obtained by using COMSOL software for a rectangular ... Read More

Simulation of Chemotractant Gradients in Microfluidic Channels to Study Cell Migration Mechanism in Silico

P. Wallin[1], E. Bernson[1], J. Gold[1]
[1]Chalmers University of Technology, Applied Physics, Biological Physics, Gothenburg, Sweden

Cell migration of endothelial cells along gradients is an important process in vivo and an interesting target for cancer therapeutics. Microfluidics offer very powerful tools to study such migration processes in detail in the lab. In this study, we describe a model to simulate molecular ... Read More

Simulation Organogenesis in COMSOL: Deforming and Interacting Domains

D. Iber[1], D. Menshykau[1]
[1]D-BSSE, ETH Zurich, Basel, Switzerland

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. ...

Modeling an Enzyme Based Electrochemical Blood Glucose Sensor with COMSOL Multiphysics

S. Mackintosh[1], J. Rodgers[1], S.P. Blythe[1]
[1]Lifescan Scotland, Inverness, Scotland

This paper describes the modeling of a blood glucose sensor using COMSOL Multiphysics. Chemical species interaction and diffusion, coupled with electrochemical oxidation of multiple blood species produced a powerful working model used in developing and refining a range of blood glucose ...

Laser Activated Gold Nanorods for the Photothermal Treatment of Cancer

F. Rossi[1], F. Ratto[1]
[1]CNR - Institute of Applied Physics "Nello Carrara", Sesto Fiorentino, Italy

Photothermal therapy through Gold Nanorods (GNRs) is a new approach for the minimally invasive treatment of cancerous tissue. In order to design the proper settings, it is important to study the thermal effect that are induced close to the nanoparticle (nanoscale model), in the close ... Read More

Computational Modeling and Simulation of the Human Duodenum

B. Hari[1], S. Bakalis[1], P. Fryer[1]
[1]The University of Birmingham, School of Chemical Engineering, Edgbaston, Birmingham, United Kingdom

Worldwide attention in the computational modeling and simulation of the human intestine is increasing in order to help understand its complex behavior and improve health. Computational fluid dynamics is an essential tool to understand the mechanics and transport phenomena of the human ... Read More

Microwave Inactivation of Bacteria Under Dynamic Heating Conditions in Solid Media

S. Curet[1], M. Mazen Hamoud-Agha[1]
[1]GEPEA, UMR 6144, CNRS, ONIRIS, Université de Nantes, Nantes, France

In this study, COMSOL®4.2a is used to model a microwave heating process in a TE10 rectangular waveguide. The sample consists of a small cylindrical Ca-alginate gel (D = 8 mm, H = 10 mm) inoculated with bacteria Escherichia Coli K12. The sample is placed along the microwave propagation ... Read More

Particle Tracing: Analysis of Airborne Infection Risks in Operating Theatres

P. Apell[1], S. Hjalmarsson[1], T. Lindberg[1], I. Wernström[1], Y. Tarakonov[1], A. Erichsen Andersson[2], M. Karlsteen[1]
[1]Department of Applied Physics, Chalmers University of Technology, Göteborg, Sweden
[2]Sahlgrenska University Hospital, Department of Anesthesia, Surgery and Intensive Care, Göteborg, Sweden

Patients undergoing surgery are sensitive to infections. The operation staff may spread 10^4 particles per person per minute, of which ten percent are presumed bacteria-carrying. We visualize the influence of the personnel on the air and particle flows for the two most common ventilation ... Read More

Electric Field Density Distribution for Cochlear Implant Electrodes

N.S. Lawand[1], J. van Driel[2], P.J. French[2]
[1]Electronic Instrumentation Laboratory (EILab), Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS), Delft University of Technology, Delft, The Netherlands
[2]Delft University of Technology, Delft, The Netherlands

Cochlear Implants are implantable devices which bypasses the non-functional inner ear and directly stimulates the hearing nerve with electric currents thus enabling deaf people to experience sound again. Implant electrode array design is limited in electrode count, due to their large ... Read More
