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 ... Saiba Mais

Thermomechanical Properties of Elastomeric Stamps for Micro-Transfer Printing Applications novo

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 ... Saiba Mais

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

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 ... Saiba Mais

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

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 ... Saiba Mais

Electrostatic Zipping Actuation of a Three-Chamber Peristaltic Micropump novo

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 ... Saiba Mais

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

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, ... Saiba Mais
