Magnetostatic-Magnon Sensors for Microwave Microscopy of Biological Structures new
Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is ... Read More
Design and Simulation of MEMS Anemometer
Wind speed measurement is a very important factor in various fields such as aeronautics, meteorology and farming. The conventional wind sensor comprises of small mechanical apparatus such as propeller and cup anemometers, or consists of thermal element such as hot wire anemometers, or ... Read More
Simulating Corrosion in a Crevice of Commercial Pure Titanium
Implant devices are assistive devices surgically placed in the human body to restore the functionality of organs and tissues. Metallic implants are often used for load bearing applications including the hip and knee joints. To allow maximum flexibility during surgery for surgeons to pick ... Read More
Design, Simulation, and Fabrication of Thermal Angular Accelerometers
This abstract introduces a sensor design for detecting angular acceleration in a single plane using thermal convection. The working principal of the device is based on probing temperature profile changes along a micro-torus caused by angular acceleration. By properly choosing the ... Read More
A Study for Developing a Cryostat for Circuit Testing at Low Temperatures
A simulation study has been performed, using COMSOL Multiphysics software, for cooling and heating a FR4 PCB and thereafter developing a controller for maintaining the PCB at a fixed temperature for circuit testing at low temperatures. Experimental arrangement was made to cool the PCB ... Read More
Simulation of an AlN Thin Film Resonator for High Sensitivity Mass Sensors
The objective of this paper is to show the simulation of a piezoelectric thin film device and its application as a sensor. Piezoelectric aluminum nitride thin film clamped at two ends is simulated using COMSOL Multiphysics software. The device consists of the piezoelectric thin film ... Read More
Modelagem Computacional de Difusores para Microbombas
Este trabalho trata do dimensionamento da estrutura bocal/difusor utilizando a simulação computacional com fronteira móvel. Esse tipo de simulação contempla toda estrutura da bomba, isto é, câmara de bombeamento, difusor e área de dispersão de fluxo, de modo a contabilizar o refluxo em ... Read More
Simulation of Gas Injection with the Level Set Method
The physical mechanisms that operate in gas injection are complex, since the bubble formation at submerged orifices involves a wide range of length and time scales, bubble coalescence occurs, rapid pressure variations around the gas bubble produce the wobbling of the bubble, as well as ...
