Air bearings are special type of bearings which provide nearly zero friction between two surfaces. This is achieved by a compressed layer of gas between the surfaces. This study presents a modeling technique for an Air bearing component. COMSOL Multiphysics® is used to efficiently solve a coupled Fluid-Structure Interaction analysis. Computational time is significantly reduced compared to ...

Tuberculosis is infectious disease caused by various strains of Mycobacterium tuberculosis. The detection is very difficult because their mechanism is not well understood, and it is mainly based on the γ interferon which is normally secreted by the T-cell of the body. The RD1 region is genomic and is present in all strains of Mycobacterium tuberculosis. The ESAT-6/CFP-10 complex is secreted by ...

Energy harvesting from ambient vibrations has become an interesting topic for powering wireless sensor networks. Resonant microdevices based on MEMS have become of central importance at low frequency. The power produced at resonance is at least one order of magnitude larger than off frequency power since the largest strain is obtained at resonance. In order to obtain large strain for efficient ...

We present an optimized and efficient design of an electrohydrodynamic (EHD) micropump for high performance in microscale and biological applications. We are targeting two major applications, a parylene C design for electrically-actuated medicine delivery, and a silicon-based pump design for on-chip cooling of microprocessors and SOCs. The EHD micropump works on the movement of microscale ...

In this paper some discrete parts of a valveless piezoelectric micropump for drug delivery system is designed and simulated. The core components of the micropump are actuator unit that converts the reciprocating movement of a diaphragm actuated by a piezoelectric actuator into a pumping effect and Nozzle/diffuser elements that are used to direct the flow from inlet to outlet. Simulations are ...
Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection sensitivity may not be sufficient when the size of the detection target is in nanoscale. To change this, we use ...

The piezoresistance effect is defined as change in resistance due to applied stress. Silicon has a relatively large piezoresistance effect which has been known since 1954. A four point bending setup is proposed and designed to analyze the piezoresistance effect in p-type silicon. This setup is used to apply uniform and uniaxial stress along the crystal direction. The main aim of this work is to ...

A logic gate performs a certain Boolean logic operation on one or more logical inputs and produces a single logical output. The logic values are either “true” or “false.” Logic gates are bistable devices, that is, they may yield one of these two possible stable outputs. The NAND logic is a universal gate; any logic operation can be performed with various combinations of NAND logics. Many ...

Achieving passive device working over two GHz bands for next generation mobile phone has been strongly desired. This paper investigated the spurious mode suppression for the BAW resonator. The border-frame technique which has been proposed in many literatures is examined here numerically. It was found that the present finite-element analysis using COMSOL Multiphyiscs® was validated via ...
