Calculation of Surface Acoustic Waves on a Piezoelectric Substrate using Amazon™ Cloud Computing

U. Vogel [1], M. Spindler [1], S. Wege [1], T. Gemming [1]
[1] Leibniz Institute for Solid State and Materials, Dresden, Germany

In this work, we seek to simulate SAWs for a better understanding and to benchmark the currently available cloud computing possibilities of COMSOL Multiphysics® software. By using the MEMS module we demonstrate 3D models with reduced geometry to achieve principle information about the ... En savoir plus

µHeater on a Buckled Cantilever Plate for Gas Sensor Applications

A. Arpys Arevalo Carreno[1], E. Byas[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Mecca, Kingdom of Saudi Arabia

In semiconductor gas sensors, the base of the gas detection is the interaction of the gaseous species at the surface of the semiconducting sensitive material. Since the chemical reactions at the surface of the sensor material are functions of temperature. We simulate our µHeater design ... En savoir plus

Design and Analysis of Multilayered MEMS Microphone Using COMSOL Multiphysics®

Saranya srinivasa raghavgan[1], Sowmya Srinivasa raghavan[1], Shruti Venkatesh[1]
[1]Rajalakshmi Engineering College, Chennai, India

In this project, we report a design of MEMS microphone that is based on the application of porous silicon in improving the sensitivity of bulk micro machined capacitive pressure sensors. The property of a low Young’s modulus of porous silicon and its dependence on porosity have been ... En savoir plus

Nondestructive Testing of Composites Using Model Based Design

E. Nesvijski[1]
[1]ACOUSTICS@MBD CONSULTANTS, LLC, Westborough, MA, USA

There is a practical interest among composite materials manufacturers to high-speed accurate non-destructive evaluation (NDE) technology for voids inspection when these voids are natural components of such complex structures like resin insulated layer of double-sided copper-clad ... En savoir plus

A Finite Element Model of Shear Wave Propagation Induced by an Acoustic Radiation Force Impulse

R. De Luca[1,2], J. Fromageau[1], H.W. Chan[1], F. Marinozzi[2], J. Bamber[1]
[1]Institute of Cancer Research and Royal Marsden Hospital, Sutton, England, United Kingdom
[2]Sapienza University of Rome, Dept. of Mechanical and Aerospace Engineering, Rome, Italy

Shear wave elastography is an innovative technique used in combination with the traditional ultrasound imaging to improve the specificity of cancer imaging. A two-dimensional finite element model (FEM), composed of realistic boundary conditions, was developed in COMSOL Multiphysics® to ... En savoir plus

Platform Isolation Using Out-of-Plane Complaint Mechanisms

A. Arevalo[1], E. Rawashdeh[1], I. G. Foulds[2]
[1]Computer, Electrical & Mathematical Sciences & Engineering Division (CEMSE), King Abdullah University of Science & Technology, Thuwal, Saudi Arabia
[2]School of Engineering, University of British Columbia - Okanagan, Vancouver, BC, Canada

This paper reports the structural solid mechanic simulation of a MEMS out-of-plane platform that provides thermal and electrical isolation for a device built on it. When assemble, the platform lifted for approximately 400 μm above the substrate level. A mechanical stress analysis is then ... En savoir plus

Simulation of a Micro-Scale Out-of-plane Compliant Mechanism
