Orientation of Piezoelectric Crystals and Acoustic Wave Propagation

G. Zhang[1]
[1]Clemson University, Clemson, SC, USA

Surface acoustic wave (SAW) devices are commonly used as wireless filters, resonators, and sensors. The confinement of acoustic energy near the surface of a piezoelectric substrate in a SAW sensor makes it highly sensitive for discerning surface perturbation. As sensors, SAW devices have ...

Modeling of Electro-Thermal Microbolometer for Thermal Imaging

A. Nowicki [1], A. Bennecer [1],
[1] Mechanical Engineering, University of Northampton & Gdańsk University of Technology, Gdańsk, Poland
[2] Engineering, University of Northampton, Northampton, United Kingdom

A Microbolometer is a specific type of uncooled infrared radiation detector used in thermal cameras, which converts the incoming energy into a proportionate electrical signal, which is then amplified, processed and displayed, typically on the thermal camera’s LCD viewer. The main ... En savoir plus

Topology Optimization of a Gaseous Photoacoustic Spectroscopy Cell Using COMSOL Multiphysics®

R. Haouari [1], V. Rochus [2], L. Lagae [1], X. Rottenberg [2],
[1] Imec & KU Leuven, Leuven, Belgium
[2] Imec, Leuven, Belgium

It is known that photoacoustic spectroscopy shows the highest signal-to-noise ratio compared to other spectroscopy techniques. This is due to an orthogonal detection scheme: while exciting with light we monitor soundwaves. In gaseous phase, the use of an acoustic chamber called cell ... En savoir plus

2D Simulation of Crimping Process for Electric Vehicle Battery Charge Cable

O. Ozgonenel [1], O. Bostan [2], S. Guzel [2],
[1] Ondokuz Mayis University,Samsun,Turkey
[2] DE-KA, Kocaeli, Turkey

Of utmost importance in appliance design and manufacture are the features for protection from fire and for personal safety. Appliance engineers are continually in pursuit of better,longer-life appliances that will provide both lower cost to the consumer and lower energy consumption. ... En savoir plus

Towards the Modeling of Microgalvanic Corrosion in Aluminum Alloys: the Choice of Boundary Conditions

N. Murer[1], N. Missert[2], and R. Bucchheit[1]

[1]Fontana Corrosion Center, Ohio State University, Columbus, OH, USA
[2]Sandia National Laboratories, Albuquerque, NM, USA

Aluminum alloys in near-neutral, mildly aggressive solutions, undergo damage accumulation during corrosion, mostly due to the presence of micrometer-sized constituent intermetallic particles (IMP) that create a microstructural discontinuity at which localized corrosion occurs. The ... En savoir plus

MEMS Electrostatic Acoustic Pixel

A. Arevalo [1], D. Conchouso [1], D. Castro [1], I. G. Foulds [2],
[1] Computer, Electrical, & Mathematical Sciences & Engineering, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia
[2] The University of British Columbia, School of Engineering, Vancouver, BC, Canada

The growth of the electronics industry demand better components for the electronic systems. Such components need to be improve to keep up with the evolution of the digital era. The loudspeaker design has not been changed for almost a century [1-5]. The acoustic transducer is the last ... En savoir plus

Micro cooling channel heat sinks designed by topology optimization

Hao Li [1], Xiaohong Ding [1], Dalei Jing [1], Min Xiong [1],
[1] University of Shanghai for science and technology

As a key component of MEMS, microprocessor with high computing performances is facing with severe thermal challenge due to the increasing power density, miniaturization as well as higher operating temperature requirements, and thermal management in corresponding fields has become one of ...

Accelerated Electrochemical Machining Tool Design

B. Skinn [1], T. Hall [1], S. Snyder [1], K. P. Rajurkar [2], E. J. Taylor [1]
[1] Faraday Technology, Inc., Clayton, OH, USA
[2] University of Nebraska, Lincoln, NE, USA

Electrochemical machining (ECM) is a manufacturing technology that allows metal to be precisely removed by electrochemical oxidation and dissolution into an electrolyte solution. ECM is suited for machining parts fabricated from “difficult to cut” materials and/or parts with complicated ... En savoir plus

Resistive Losses in a 3D Coil

U. Hafner [1],
[1] Baumer Electric AG, Frauenfeld, Switzerland

In this presentation it is shown how an axially symmetric coil can be simulated in a non-symmetric environment. A rotationally symmetric coil can be simulated by using a 2D model. Doing so the serial equivalent resistance of the coil is obtained among other results. The influence of the ... En savoir plus
