MEMS microphones consist of a conductive backplate and a conductive flexible membrane. The backplate and the membrane are at a certain distance from each other to be interpreted as parallel plates of a capacitor. When a bias voltage is applied to the electrodes, membrane deflection ...

Numerical study of fluid flow and heat transfer in a finite three-dimensional rectangular, horizontal duct of length to width, and length to height ratio of 12:1 is investigated in this study. The left wall of the duct is uniformly heated while the right, top, and bottom walls are ... Per saperne di più
Introduction: Design of a thermally driven actuator used in Micro Electro Mechanical Systems (MEMS) with two different metal materials is discussed. To achieve best performance of the thermally driven actuator in this work, it is desired to use a metal material with both high coefficient ... Per saperne di più
Incompressible flow field past a circular cylinder within parallel plate channel is very important in industry and science. As well known, beyond the Reynolds number based on the diameter of the cylinder and uniform flow velocity of 40, flow past a circular cylinder cannot hold its two ... Per saperne di più
Flow past a circular cylinder arises in many engineering applications, but there is significantly less work studying flow past a cylinder in a confined domain, such as pipe flow or flow in a plane channel. There are many applications where the scaling of a particular problem requires ... Per saperne di più
Micro shutter array (MSA) is a programmable optical spatial filtering device fabricated by micro electro-mechanical system (MEMS) technology. It was originally developed for James Webb Space Telescope (JWST) to enable multi-object spectroscopy and operated by a moving magnet. Next ... Per saperne di più
Organic Thin Film Transistors are simulated for gas sensing application. The simulation is performed using COMSOL Multiphysics® simulation software's Semiconductor Module. Drift-diffusion (DD) simulation model is used in which the basic equations used are similar to those used for a ... Per saperne di più
With the scaling of semiconductor devices into the nanometer regime, short channel effects are an ever-present issue. Among these effects are threshold voltage variation with channel length, reduced output resistance, punch-through and hot-electron degradation. The effect of constant ... Per saperne di più
Metallic foams can be plastically deformed to dramatically alter the material’s mass density, microstructure, and bulk mechanical properties. This work investigates the plastic deformation of open-cell aluminum foams numerically, using high fidelity models of metallic foam constructed ... Per saperne di più
For many decades Helium-3 (3He) and Argon gas filled detectors have been used for neutron and gamma detection. Detection requires the generation of electrons which can then be measured by electronic means. These electrons are generated either directly through gamma ionization of a gas ... Per saperne di più
