Experimentally Matched Finite Element Modeling of Thermally Actuated SOI MEMS Micro-Grippers Using COMSOL Multiphysics

M. Guvench[1], and J. Crosby[1]
[1]University of Southern Maine, Gorham, Maine, USA

In “Micro-Electro-Mechanical-Systems” shortly known as MEMS, one of the most important and effective principle of creating transduction of electrical power to displacement force is thermal expansion. A slim beam of MEMS material, typically Silicon, is heated by the application of ... 詳細を見る

Finite element analysis approach for optimization of enzyme activity for enzymatic bio-fuel cell

C. Wang[1], Y. Song[1], Y. Parikh[1], and J.H. Yang[1]
[1]Department of Mechanical & Materials Science Engineering, Florida International University, Miami, Florida, USA

Enzymatic biofuel cells (EBFCs) are miniature implantable power sources, which use enzymes as catalysts to perform redox reaction with biological fuels such as glucose. In this study, we focused on a three dimensional EBFC chip with highly dense micro-electrode arrays, fabricated by ... 詳細を見る

Model of a Filament Assisted CVD Reactor

J. Brcka[1]

[1]TEL US Holdings, Inc., Technology Development Center, Albany, New York, USA

In this presentation we are dealing with the computational fluid model of a Filament Assisted Chemical Vapor Deposition (FACVD) reactor. Proposed strategy in this study involved several steps: (a) development a computational model for FACVD process capable to describe and obtain with ... 詳細を見る

Finite Element Analysis of Microscale Luminescent Glucose Sensors in the Skin Dermis

S. Ali[1], and M. McShane[1]
[1]Department of Biomedical Engineering, Texas A&M University-College Station, Texas, USA

With the rising predominance of diabetes, successful management of blood glucose levels is increasingly important. Key efforts have focused on the development of optical microscale glucose sensing systems based on the encapsulation of glucose oxidase within microspheres coated with ... 詳細を見る

Fluid Dynamics of Blood Flow during Reperfusion and Post-conditioning

T. Merrill[1], A. La Barck[1], and J. Docimo[2]
[1]Rowan University, Glassboro, New Jersey, USA
[2]FocalCool, LLC, Mullica Hill, New Jersey, USA

Reperfusion injury is caused by the rapid restoration of blood flow to oxygen-starved tissue. Animal studies show that intermittent periods of occlusion (also called post-conditioning) during reperfusion can limit tissue damage to vital organs such as the heart and brain. These studies ... 詳細を見る

Linear Convection and Conduction in Cylinders of Water Exposed to Periodic Thermal Stimuli

R.E. Tosh[1], and H.H. Chen-Mayer[1]
[1]National Institute of Standards and Technology, Gaithersburg, Maryland, USA

Primary reference standards for determining absorbed dose to water in radiotherapy beams used at cancer clinics and hospitals ultimately must make reference to the temperature change in water produced by ionizing radiation. The most direct experimental technique for this purpose is water ... 詳細を見る

Modeling of Nerve Stimulation Thresholds and Their Dependence on Electrical Impedance with COMSOL

P. Krastev[1], and B. Tracey[1]
[1]Neurometrix, Inc., Waltham, Massachusetts, USA

Nerve localization is important for applications in regional anesthesia. Localization is achieved by stimulating the nerve with an electric field produced by a current from a needle inserted into the body of the patient, close to the target nerve.  Modeling of the electric field in close ... 詳細を見る

Coupled Heat and Mass Transfer Processes in Enclosed Environments

J.L.Wilson[1], and R. Dwivedi[1]

[1]New Mexico Institute of Mining and Technology, Socorro, New Mexico, USA

Geothermally driven natural convection in enclosures is a ubiquitous process occurring in many physical environments such as caves, mines, etc. We have numerically simulated laminar and turbulent natural convection in isolated air-filled cavities, buried in a more conductive rock mass. ... 詳細を見る

Rapid Prototyping of Biosensing Surface Plasmon Resonance Devices using COMSOL & Matlab software

J.J. Dubowski[1], and D.Carrier[1]
[1]Department of Electrical and Computer Engineering, Université de Sherbrooke, Quebec, Canada

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  COMSOL Multiphysics and MATLAB software ... 詳細を見る

Modeling Two-Phase Electrophoresis

W. Clark[1], and M. Lindblad[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, Massachusetts, USA

Two-phase electrophoresis is a separation method that combines aqueous two-phase partitioning with electrophoresis and has promise for large scale recovery of biological products. Aqueous two-phase systems formed by adding two polymers, like dextran and polyethylene glycol, to water ... 詳細を見る
