Viscous damping has a significant effect on dynamic performance of the resonators operating within fluid. This work is aimed to find the viscous damping for MEMS torsional paddle operating in air. Interaction of moving structure with the fluid requires a complicated and challenging ... En savoir plus
The microband design of microelectrodes is a cost-effective and easily-fabricated compromise combining convergent mass transport, due to microscale width as a critical dimension, and high output currents due to the macroscopic length. Among the various techniques available for microband ... En savoir plus
This poster focuses on the development of a capacitive pressure sensor for condition monitoring applications. One method to measure vibrations is to mount an pressure sensor on the vibrating machinery or object and measure the pressure exerted due to vibrations. Measured pressure level ... En savoir plus
引言: 对于微流控分选芯片而言,分支出口的位置、宽度等几何参数会直接影响到粒子分选精度与回收效率。但是,遗憾的是,对于流道各分支出口位置的高效设计方法却鲜有报道。当前的设计方法主要是对每一种目标粒子直接进行轨迹仿真[1~7]。但这种方法的运算成本巨大,如果粒子分散体系涉及到的粒径种类繁多且流道结构复杂,那么对每种粒径都进行仿真分析将会使得计算量与计算精度之间的矛盾愈加尖锐;而且,每引入一种没有被仿真研究过的粒径,都要对其重新进行仿真运算,运算成本巨大[8~10]。 据此,本文提出了一种结合有限元分析仿真与系统辨识方法的粒子出射位置预测方法 ... En savoir plus
Biosensors based on silicon nanowires are of great interest for ultrasensitive biomolecular recognition of disease specific markers for early stage diagnosis [1]. However, there are limitations on the performance of these nanosensors in solutions at high ionic strength. This is because ... En savoir plus
In this study, COMSOL Multiphysics® software was used to simulate the surface response to excitation method (SuRE). An aluminum beam with a piezoelectric element bonded is modeled using the COMSOL Acoustics Module. A frequency domain sweep study was performed to simulate the sweep sign ... En savoir plus
Fluorescence Diffuse Optical Tomography (FDOT) uses Near Infra-Red (NIR) light to monitor physiological changes in internal organs. NIR light being less energetic in nature can be used for continuous monitoring of tumor infected biological tissue, neonatal brain and many such ... En savoir plus
Lubricant oil is used to ensure proper functioning of industrial machinery such as turbines, gears, bearings and compressors. Oil analysis is used to detect and quantify the presence of wear metals and other contaminants in the lubricant of oil wetted systems, by sensing the change in ... En savoir plus
One of the most promising categories of semiconductor-based sensors is organic electrochemical transistor (OECT), which consists of three electrodes (Source, Drain and Gate) and two active layers: electrolyte and conductive polymer. Despite the fact that OECT attracts a lot of attention ... En savoir plus
Strain gauges have been extensively used for detecting strain in various applications. Double-ended tuning fork (DETF) strain gages present better performance characteristics than standard foil gauges, including higher sensitivity, smaller size and higher resolution. This study focuses ... En savoir plus
