Finite Element Analysis of Planar Microcoil Based Induction-balance Magnetic MEMS Sensor
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 ... Per saperne di più
Optimization of Microfabricated 2D Planar Spiral Microcoils for the Micro NDT of Grinding Burn
Cylindrical grinding has become an integral part of machining of workpieces with an ultra-high precision and higher throughput. The grinding process involves the mechanical interaction of the grinding blade with the workpiece at relatively higher rotation speeds, with a higher energy ... Per saperne di più
Multiphysics Simulation of Internal Discharge in Nanodielectric
This research work investigates the effect of inclusion of small amount (0%, 2% and 6%) of natural Nano fillers on the internal field properties and discharge characteristics of polypropylene films. 3D Models are built to simulate field properties and internal charge in natural ...

3D Modeling of Nanocomposites
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 ... Per saperne di più
Thermomechanical Properties of Elastomeric Stamps for Micro-Transfer Printing Applications
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 ... Per saperne di più
Silicon Nitride Corrugated Membrane with High-Width-Aspect-Ratio for MEMS Microphones
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 ... Per saperne di più
Simulation of a Scaled-up Deformable Mirror System Driven by MEMS-Based Lorentz Actuator Arrays
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 ... Per saperne di più
Electrostatic Zipping Actuation of a Three-Chamber Peristaltic Micropump
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 ... Per saperne di più
Finite Element Modeling of an AlGaN/GaN Based VOC Sensor Using COMSOL®
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, ... Per saperne di più
Understanding the Physics of Droplet Electrocoalescence in a Microtrap
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 ... Per saperne di più
