Finite Element Analysis of Planar Microcoil Based Induction-balance Magnetic MEMS Sensor

Krishnapriya S¹, Suja K J², Rama Komaragiri³
¹Department of ECE. Muthoot Institute of Technology, India
²NIT Calicut, Calicut, Kerala India
³Bennett University, Greater Noida, Uttar Pradesh, India

Two transmitting planar microcoils (TX1, TX2) and one receiving microcoil (RX) are employed as shown in Fig.1 formed in induction-balance configuration. RX-Coil is positioned in such a way to achieve primary field suppression in RX-Coil’s region. Meaning, a magnetic cavity is created in ... Mehr lesen

Optimization of Microfabricated 2D Planar Spiral Microcoils for the Micro NDT of Grinding Burn

MA. Rab¹, F. Alam²
¹Norfolk State University, Norfolk, VA, USA
²UnitedHealth Group, Minneapolis, MN, USA

Current research focus on improvement of electrical, mechanical, surface characteristics of polypropylene films by incorporation of nanoparticles into the polymer matrix of the film. We built 3D model of polypropylene Nanocomposites made of polypropylene matrix and incorporating various ... Mehr lesen

Thermomechanical Properties of Elastomeric Stamps for Micro-Transfer Printing Applications

C. Reyes¹, K. Oswalt ¹, J. Thostenson¹, J. Roe¹, D. Gomez¹
¹X-Celeprint, Durham, NC, USA

Micro-transfer printing (MTP) enables mass-transfer of wafer-level chips having lateral dimensions ranging from 3 x 7 um to 650 x 650 um to a nonnative substrate. This is accomplished with an elastomeric stamp containing micrometer scale posts that have been precisely defined using ... Mehr lesen

Silicon Nitride Corrugated Membrane with High-Width-Aspect-Ratio for MEMS Microphones

Shubham¹
¹Knowles Electronics, Itasca, IL, USA

Micro-Electro-Mechanical Devices such as acoustics sensors, finger print sensors, tunable capacitors etc. are widely used in commercial applications. The pressure sensors use membranes which deflect upon applied pressure load. The most important aspect of any pressure sensor is its ... Mehr lesen

Simulation of a Scaled-up Deformable Mirror System Driven by MEMS-Based Lorentz Actuator Arrays

B. Park¹, A. J. Bergren¹, M. Belov¹, G .Burley², C. Shafai³
¹Nanotechnology Research Centre, Edmonton, Canada
²NRC-Herzberg Astronomy & Astrophysics, Victoria, BC, Canada
³Department of Electrical and Computer Engineering, University of Manitoba, Winnipeg, MB, Canada

This paper presents the design and simulation results of a MEMS-actuated deformable mirror (DM) consisting of a 20 × 20 Lorentz-force actuator array bonded to a flexible mirror. The DM is the critical component of an Adaptive Optics (AO) system targeted for ground-based telescope ... Mehr lesen

A. Eden¹, S. MacKenzie¹, D. Huber¹, S. Pennathur¹, S. Stettler²
¹University of California, Santa Barbara, Santa Barbara, CA, USA
²University of California, Santa Barbara, Santa Barbara, CA, USA and Ecole Polytechnique Federale de Lausanne, Lausanne, Switzerland

While electrostatic actuators feature prominently among the most widely employed classes of actuators for microelectromechanical systems (MEMS), conventional embodiments of these devices (e.g., parallel plate structures) notoriously suffer from several significant drawbacks. Most ... Mehr lesen

Finite Element Modeling of an AlGaN/GaN Based VOC Sensor Using COMSOL®

B. Uppalapati¹, G. Koley¹, A. Kota²
¹Clemson University, Clemson, SC, USA
²University of Dayton, Dayton, OH, USA

Volatile organic compounds (VOCs) are a large group of chemicals that can be found in many products that we use to build and maintain our homes. Some of the VOCs such as benzene, formaldehyde, ethylene glycol, etc. can be found in our everyday life in the form of paints, cleaning agents, ... Mehr lesen

Understanding the Physics of Droplet Electrocoalescence in a Microtrap

B. Koppolu¹, S. P. Burugupally¹, F. B. Memon¹
¹Wichita State University, Wichita, KS, USA

Droplet-based microfluidic systems are emerging as an ideal platform for the high-throughput screening of eukaryotic cells aimed to understand the complex, multidimensional, and dynamic biological processes [1]. Here, two aqueous droplets – each containing a eukaryotic cell – suspended ... Mehr lesen
