Modeling Inertial Focusing in Straight and Curved Microfluidic Channels

J. Martel[1], N. Elabbasi[2], D. Quinn[2], J. Bergstrom[2], M. Toner[1]
[1]BioMEMS Resource Center, Massachusetts General Hospital, Boston, MA, USA
[2]Veryst Engineering, Needham, MA, USA

Inertial focusing is a promising microfluidic technique for separating and concentrating cells of interest, processes routinely utilized in many medical procedures. This phenomenon is characterized by suspended particles in a flow spontaneously migrating across streamlines to equilibrium ... Read More

Modeling and Simulation of High Permittivity Core-Shell Ferroelectric Polymers for Energy Storage Solutions

N. Badi[1], R. Mekala[1]
[1]University of Houston, Houston, TX, USA

The dielectric properties of ferroelectric PVDF polymer embedded core-shell (Al-Al2o3) nanoparticle is simulated using COMSOL Multiphysics® software. Significant increase in electrical permittivity of the composite at percolation threshold (K = 2800) is achieved when compared to ... Read More

Simulation of Fast Response Thermocouple for the Nuclear Reactor Core

K. Dusarlapudi[1], B. K. Nashine[2], D. Bai[3], and C. S. Babu[1]
[1]KL University, Vaddeswaram, Guntur, Andhra Pradesh, India
[2]E.D&S.S, IGCAR Kalpakkam, India
[3]VIT, Vellore, India

Thermocouples have been used for measurement of temperature ever since the discovery of Seebeck effect. Though the voltage output of a thermocouple is a function of the temperature difference between hot and cold junctions, the response time and the magnitude of voltage depends on the ... Read More

COMSOL Multiphysics^® as a General Platform for the Simulation of Complex Electrochemical Systems

A. Lavacchi[1]
[1]Department of Chemistry, University of Firenze, Sesto Fiorentino, FI, Italy

Microelectrodes demonstrate that modeling is crucial for understanding the behavior of complex electrochemical systems. The use of the finite element methods in electrochemistry may be of much more general interest for its ability to handle complex geometries. In this context a ... Read More

Matching 4D Porous Media Fluid Flow GeoPET Data With COMSOL Multiphysics Simulation Results

J. Lippmann-Pipke, J. Kulenkampff, G. Marion, and M. Richter
Helmholtz-Zentrum Dresden
Rossendorf, Institut of Radiochemistry
Research Site Leipzig
Reactive Transport Division
Leipzig, Germany

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import ... Read More

Coupling of Wired PCB With Microwave Radiation – 3D Simulation and Experimental Valuation

T. D. Bui[1], F. Bremerkamp[2], and M. Nowottnick[2]
[1]Department of Automobile Engineering, Thanh Do University, Ha Noi, Vietnam
[2]Institute of Electronic Appliances and Circuits, Department “Reliability and Safety of Electronic Systems”, University of Rostock, Rostock, Germany

Modern electronic assemblies and printed circuit boards (PCB) with their sensitive structures and elements have to be protected against environmental influences by conformal coating or casting compounds. In this case the main challenge is the simultaneous curing of the polymers and the ... Read More

Electrical and Thermal Analysis of an OLED Module

J. Kundrata[1], A. Baric[1]
[1]Faculty of Electrical Engineering and Computing, University of Zagreb, Zagreb, Croatia

This paper presents the electrical and thermal analysis of an OLED module. The OLED module consists of the OLED tile and the DC-DC converter incorporated in its backplane. The DC-DC converter is realized as an integrated circuit and its inductor is embedded in the the backplane. The DC ... Read More

Fluid-Structure Interaction Modeling for an Optimized Design of a Piezoelectric Energy Harvesting MEMS Generator

I. Kuehne[1], A. van der Linden[2], J. Seidel[1], M. Schreiter[1], L. Fromme[2], and A. Frey[1]
[1]Siemens AG, Corporate Research & Technologies, Munich, Germany
[2]Comsol Multiphysics GmbH, Göttingen, Germany

This paper reports the design of a piezoelectric energy harvesting micro generator for an energy autonomous tire pressure monitoring wireless sensor node. For our design we use a piezoelectric MEMS generator approach without additional mass. The intrinsic mass of the cantilever is in the ... Read More

Flow-induced Vibrations of the Uvula and its Implication on Snoring

J. Xi[1], Q. M. Mohamad[1], Y. E. Yuan[1], J. Rohlinger[1]
[1]Mechanical and Biomedical Engineering, Central Michigan University, Mount Pleasant, MI, USA

Flow-induced uvula deformation considerably altered the flow dynamics inside the nose. For a weak soft palate, complete flow occlusion can occur (sleep apnea). Vibration of the airway structures is crucial to better understand snoring generation mechanisms and breathing-related ... Read More

Optimization of Design Parameters of a Novel MEMS Strain Sensor used for Structural Health Monitoring of Highway Bridges

H. Saboonchi, and D. Ozevin
Civil Engineering Department
University of Illinois at Chicago
Chicago, IL

The novel Micro Electro Mechanical System (MEMS) based Piezoresistive stain sensor is presented in this paper. The main goal of this sensor is to monitor the localized strain in the highway bridges especially near the crack tips. Monitoring the crack growth on the bridges can lead to ... Read More
