Working fluids (engine oil, transmission fluid, hydraulic fluid, coolants, etc.) become contaminated in use. To ensure that the equipment is not damaged by the contaminated fluid, the fluid is typically removed and replaced periodically. For large groups of machines, the used fluid is ... Read More
Plastic packages, coated with Epoxy Molding Compound (EMC) can provide an economic and versatile protection to the integrated circuits (IC) from mechanical damage. A major drawback of molded packages is that they are not hermetic and are prone to absorb moisture from external ... Read More
Blind cave fish are capable of sensing flows and movements of nearby objects even in dark and murky water conditions with the help of arrays of pressure-gradient sensors present on their bodies called lateral-lines. To emulate this functionality of lateral-lines for autonomous underwater ... Read More
The Purpose of this paper is to develop a thermal model using COMSOL Multiphysics® software that aims to get an idea of the heat flow around the ASIC, as well as to address the thermal issues for integrated circuits at the tongue board. However, we need sources of heat simulations to map ... Read More
Human made mechanical resonators have been around for a thousand years. Early applications included musical instruments and chronographs operating in millihertz to kilohertz frequencies while more recent interest has turned ultra-high frequency resonators and oscillators suitable for ... Read More
The specular and diffuse reflection properties of sunlight at the rear surface of silicon solar cells with various degrees of roughness are computed by solving the Maxwell and material equations in two dimensions, using the COMSOL RF Module. The model is tested on planar Si/SiO2/air ... Read More
The objective of this study is to determine the locations where liquid water accumulates at cathode gas flow channels, and the corresponding operating conditions. In such way it is possible to mitigate slug flow, responsible for channel blockage and hindering the diffusion of reactants ... Read More
基于纸基微流控芯片(μPAD)的核酸提取和扩增反应需均匀稳定、快速响应的热源。半导体制冷器具有无需制冷剂和体积小等优点，可为纸基芯片提供便携式、低功耗分析平台。相较于其他传统核酸扩增与检测设备，μPAD可以借助内部纤维结构的毛细作用自驱动输送流体介质。并且，微尺度下纤维结构具备较高的比表面积，在原理上可改善常规比色、荧光等检测方法的检出限和精准度。然而，滤纸材料本征参数对试剂溶液动态扩散过程和反应结果影响很大，数值仿真模拟是μPAD性能分析和优化设计的重要途径。本文应用COMSOL®热电效应耦合模块和非等温流动耦合模块，获取芯片内部的温度场信息，评价μPAD温控系统设计 ...

The detection back-action phenomenon has received little attention in physical, chemical, and biological sensors based on nanomechanical systems. We show that this effect is very significant in ultrathin bimetallic cantilevers, in which the laser beam that probes the picometer scale ... Read More
An Ion Mobility Spectrometer is a device to analyze different components of a gas mixture. A feature of this technology is the ultra-low detection limit which can be obtained for most trace gases. Due to a limited resolution which is needed to differ between different components an ... Read More
