Design and Analysis of a Three-DOF Piezoelectric Vibration Energy Harvester

R. T. P. Reddy [1], X. Xiong [2], J. Hu [3],
[1] University of Bridgeport, Bridgeport, CT, USA
[2] Department of Electrical and Computer Engineering, University of Bridgeport, Bridgeport, CT, USA
[3] Department of Mechanical Engineering, University of Bridgeport, Bridgeport, CT, USA

Introduction: Vibration energy harvester can convert mechanical vibration energy into electrical energy and store it in battery for later use. It can create clean renewable energy from vibration movements such as walking, jumping, running, etc. This can convert energy previously wasted ... Read More

Coupling Picosecond Terahertz Pulses to a Scanning Tunneling Microscope

P. H. Nguyen [1], C. Rathje [2], G. J. Hornig [1], V. Jelic [1], C. Ropers [2], F. A. Hegmann [1],
[1] University of Alberta, Edmonton, AB, Canada
[2] 4th Physical Institute, University of Göttingen, Göttingen, Germany

Probing ultrafast processes over subpicosecond and picosecond time scales provides fundamental insight into the nature of materials. We have experimentally demonstrated terahertz (THz)-pulse-induced tunneling in a scanning tunneling microscope (THz-STM) to image surfaces with ... Read More

Maximizing Wireless Power Transfer Using Ferrite Rods within Telemetric Devices for Rodents

B. M. Badr [1], R. Somogyi-Csizmazia [1], K. R. Delaney [1], N. Dechev [1],
[1] Department of Mechanical Engineering, University of Victoria, Victoria, BC, Canada

A number of medical and research applications require implantable devices to locally stimulate internal organs and communicate the internal vital signals to the outer world. Wireless power transfer (WPT) technique is used to supply power to these devices. The power is transferred ... Read More

Designing Piezoelectric Energy Harvesting Using COMSOL Multiphysics® Software for Mouse Telemetry Device

B. M. Badr [1], K. R. Delaney [1], N. Dechev [1],
[1] Department of Mechanical Engineering, University of Victoria, Victoria, BC, Canada

Mice are important animals used for biomedical research, and are widely used to study various disease models. When studying the behavior of mice and gathering biological data from them, miniature sensors and telemetry devices are needed. These devices must provide continuous monitoring ... Read More

Acoustic Streaming Driven Mixing

N. Nama [1], P. Huang [1], F. Costanzo [1], T. J. Huang [1]
[1] Department of Engineering Science and Mechanics, Pennsylvania State University, PA, USA

Introduction - The ability to achieve rapid and homogeneous mixing at microscales is one of the essential requirements for various lab-on-a-chip applications [1]. The flow at microscales is characterized by low Reynolds number, resulting in laminar flow patterns. Thus, the mixing at ... Read More

Using High Pressure Chemical Vapor Deposition to Make Multimaterial Optical Fibers

S. Chaudhuri [1], J. V. Badding [1],
[1] Pennsylvania State University, University Park, PA, USA

Ever since its advent optical fibers have revolutionized the communication technology but apart from communication they are being used in a variety of other areas such as medical technology, sensing, laser sources in the form of fiber lasers, amplifiers, cutting and drilling, defense ... Read More

Application of COMSOL Multiphysics® Software to Model Temperature Changes in Buildings with PCM Incorporated in Their Elements

N. P. Sharifi [1], A. A. N. Shaikh [1], A. R. Sakulich [1],
[1]Department of Civil and Environmental Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

Reducing HVAC energy consumption in buildings has provoked a lot of thought and has, subsequently, drawn a lot of attention. Out of the several methods that have been introduced to achieve this goal, the usage of Phase Change Materials (PCMs) in the structural components is one of the ... Read More

3D Simulation of Laser Interstitial Thermal Therapy in the Treatment of Brain Tumors

M. Nour [1], A. Lakhssassi [1], E. Kengne [1], M. Bougataya [1],
[1] Université du Québec en Outaouais, Gatineau, QC, Canada

Abstract: Due to the restriction of the number of probes that a patient can tolerate, and the inaccurate information provided by the invasive temperature measurements, which provide information only at discrete points, a mathematical model simulation is more effective to help doctors in ...

Multiphase Laminar Flow with More Than Two Phases

W. T. Vetterling [1],
[1] Zink Imaging, Inc., Billerica, MA, USA

Introduction The COMSOL Multiphysics® software and its CFD Module have a physics interface for solving Laminar Two-Phase Flow problems using the Level Set method (1). This paper discusses how the tool may be used with more than two phases when the flow is laminar. It then introduces a ... Read More

Parameter Estimation in a Single Particle Model Using COMSOL Multiphysics® Software and MATLAB® Optimization

B. Rajabloo [1], M. Désilets [1], Y. Choquette [2],
[1] Département de Génie Chimique et de Génie Biotechnologique, Université de Sherbrooke, QC, Canada
[2] Institut de recherche d’Hydro-Québec, Varennes, QC, Canada

When it comes to study the behavior of the secondary batteries, physics-based models are more representative of the real behaviour than equivalent circuit models, especially for the estimation of the life and capacity fading. On the other hand, the complexity and computational cost of ... Read More
