Silicon-Organic-Hybrid Independent Simultaneous Dual-Polarization Modulator: Device Theory and Design

Y. D'Mello [1], M. Hui [1], J. Skoric [1], M. Haines [1], A. Kirk [1], M. Andrews [1], D. Plant [1],
[1] McGill University, Montréal, QC, Canada

The Complementary Metal-Oxide-Semiconductor (CMOS) technology is a gateway to fabricating low cost electronic and photonic components to date. The Silicon-based nanophotonics platform leverages CMOS technology to fuel the effort to provide increasingly high-speed and high-bandwidth ... Read More

A Multiphysics Model of O2 Transport and Recirculation During Venovenous Extracorporeal Life Support

S. Conrad [1],
[1] Louisiana State University Health Sciences Center, Shreveport, LA, USA

Venovenous extracorporeal life support (VV-ECLS) provides gas exchange support for severe lung failure by using an extracorporeal circuit consisting of a blood pump and an artificial membrane lung. Blood is withdrawn from a cannula placed into the inferior vena cava, and returned from ... Read More

An Examination of Wall Shear Stresses in Curved Arterial Vessels Using Bioresorbable Stents

D. W. Pepper [1], S. Pirbastami [1],
[1] University of Nevada - Las Vegas, Las Vegas, NV, USA

Bioresorbable stents are providing temporary mechanical support to keep a narrowed or blocked coronary artery open and restore the blood flow and will be gradually degraded and resorbed after the healing and remodeling of arterial wall. This new generation of stents has lower rates of ... Read More

Simulation of Acoustic Wave-Structure Interaction in a Quarter Wavelength Tube Energy Harvester

L. Melander [1], J. H. You [1],
[1] University of St. Thomas, St. Paul, MN, USA

An acoustic energy harvesting system at low frequency (~200 Hz) using lead zirconate titanate (PZT) piezoelectric cantilever plates placed inside of a quarter-wavelength straight-tube resonator has previously been studied using COMSOL and verified experimentally. When an incident ... Read More

Modeling and Simulation of Control Valves via COMSOL Multiphysics®

S. Zhuang [1],
[1] CAEaid, Inc., Austin, TX, USA

Valves are widely used to control fluid flow in various engineering applications. It’s crucial to study the flow characteristics inside the valve and the fluid-structure interaction between the fluid and valve’s sleeve for design, optimization and improvement of valves. However, because ... Read More

Modeling and Simulation of Mechanically Coupled MEMS Resonators Using COMSOL Multiphysics®

J. Wiswell [1], M. Guvench [1],
[1] University of Southern Maine, Gorham, ME, USA

Introduction: In this project, COMSOL Multiphysics® and SolidWorks® are employed to model and simulate a mechanically coupled MEMS resonator with varying masses. These resonators consist of three main components: springs on each end to allow the structure to move, a shuttle mass for ... Read More

Multiphysics Modeling of the Graphite Electrode Joint in Electric Arc Furnaces for Steel Recycling

N. May [1], M. Waldner [2],
[1] GrafTech International Holdings, Inc., Independence, OH, USA
[2] Case Western Reserve University, Cleveland, OH, USA

Electric Arc Furnaces (EAF) use graphite electrodes to strike an arc to melt scrap steel, recycling it for further use. These graphite electrodes oxidize and are consumed over time. To maintain operation new electrodes are attached to others via a joint of complex geometry and fed ... Read More

Modeled Electroformed MEMS Variable Capacitors for Cobalt Iron Alloy Magnetostriction Measurements

E. Langlois [1], P. Finnegan [1], J. Pillars [1], T. Monson [1], C. J. Pearce [1], C. St. Johns [1], M. Ballance [1]
[1] Sandia National Laboratories, Albuquerque, NM, USA

Electroplated CoFe alloys demonstrating Joule magnetostriction (i.e., a large change in material shape induced by an applied magnetic field) have been recently developed for the creation of microfabricated magnetoelastic resonators for tagging applications. This development requires a ... Read More

Design & Finite Element Analysis of Micro Electro Mechanical Capacitive Temperature Sensors

N. Z. Khan [1],
[1] Rutgers University, New Brunswick, NJ, USA

This paper presents the design and simulation of novel micrometer-scale capacitive temperature sensors, which could serve as a component for miniaturized wireless sensor nodes for the internet of things requiring structural flexibility and optical transparency. The proposed sensor design ... Read More

Multiphysics Modeling of a Minimally Invasive Tissue Ablation Methodology

J. S. Crompton [1], J. Thomas [1], K. Koppenhoefer [1],
[1] AltaSim Technologies, Columbus, OH, USA

Necrosis of human tissue can typically be obtained by exposure to temperatures below 40°C or above +50°C. However, inherent variability in tissue properties, the complexity of tissue response and dissipation of thermal energy by local perfusion or blood flow can make the development of ... Read More
