The microscopic size of MEMS devices accounts for strong coupling effects which arise between the different physical fields and forces. Micromirrors are essential parts of microswitches in fiber optic network telecommunication. They are usually 1 to 3 mm in size, fabricated from single crystalline silicon and mostly are electrostatically actuated. The objective is to design the micromirror to ...

There has been growing demand for high performance micro sensors capable of detecting nuclear radiations being released from various industries, Nuclear reactors. Radiations emitted from the radioactive materials are invisible and not directly detectable by human senses. Thus it is highly essential to work on design of bolometers with absorptive elements providing optimum sensitivity. The ...

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 ...

This paper projects a novel 3D capacitive accelerometer design to identify a severe accident and initiate airbag deployment systems. It will detect the rapid negative acceleration of the vehicle to avoid the severity of the collision. Such a device demands excellent performance in terms of sensitivity, noise immunity, linearity, bias and scale factor stability over time and environmental changes. ...

Moving nanowires through microfluidic channels under electrokinetic forces can be a valuable technique to aid in the fabrication of certain devices. The trajectories of a nanowire under the influence of an externally applied electric field have been modelled through a straight channel, through a converging channel, and around a 90° corner. In a straight channel, a nanowire initially ...

Various cantilever geometries (conventional rectangular,pi,Tandtriangular) are simulated using the Structural Mechanics module of COMSOL Multiphysics® to compare their spring constants. A layer of piezoelectric material (ZnO,AlN and PZT are modeled) is added to the cantilever and using the Piezoelectric Devices physics of COMSOL Multiphysics®, we determine the piezoelectric voltage that is ...

The newly emerging field of carbon-based MEMS (C-MEMS) attempts to utilize the diverse properties of carbon to push the performance of MEMS devices beyond what is currently achievable. Our design employs a carbon-carbon composite using nano-materials to build a new class of MEMS accelerometer that is hyper-sensitive over a dynamic range from micro-G to hundreds of G’s – far surpassing the ...
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 ...

In this work COMSOL is utilized to obtain the Mason lumped parameter model for a piezoelectric transformer (PT) design. The Mason lumped parameters are relevant in the design process of power converters. The magnitude of the impedance is simulated for a specific interleaved multilayer thickness mode PT. The PT design has been prototyped and the measurements results are compared with simulations. ...
