COMSOL Multiphysics Modeling of Rotational Resonant MEMS Sensors with Electrothermal Drive

S. Nelson[1], and M. Guvench[1]
[1]University of Southern Maine, Gorham, Maine, USA

COMSOL Multiphysics is employed to model, simulate and predict the performance of a high Q, in-plane rotational resonating MEMS sensor. The resonating sensor disk is driven by thermal expansion and contraction of the support tethers due to AC joule heating. The resonant frequency is ... En savoir plus

Underwater acoustic scattering studies on the sub-sea pressure housings

D. Nikhil Sai Prasanna¹, A. Thirunavukkarasu¹, A. Malarkodi¹, G.Latha¹

This paper presents a finite element (FE) model of the scattering studies of cylindrical pressure housings made of different metallic alloys such as aluminium, stainless steel 316L and titanium. Understanding the acoustic scattering behavior of underwater objects helps in improving ... En savoir plus

Full-Wave Simulation of an Optofluidic Transmission-Mode Biosensor

E. P. Furlani[1], N. M. Litchinitse[2], and R. Biswas[2]

[1]The Institute for Lasers, Photonics and Biophotonics, University at Buffalo, Buffalo, New York, USA
[2]Department of Electrical Engineering, The State University of New York at Buffalo,Buffalo, New York, USA

We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the ... En savoir plus

The Origin of Mass-change Sensitivity within Multi-layered, Non-uniform, Piezoelectrically-actuated Millimeter-sized Cantilever (PEMC) Biosensors: Vibrational Analysis through Experiment and Finite Element Modeling (FEM)

B.N. Johnson[1], and R. Mutharasan[1]

[1]Department of Chemical and Biological Engineering, Drexel University, Philadelphia, Pennsylvania, USA

A 3D finite element model (FEM) of the PEMC sensor was developed to characterize the modes of vibration that have demonstrated high sensitivity to mass-change in experimentally fabricated sensors. The fundamental bending mode of vibration and the 1st bending harmonic are predicted at 10 ... En savoir plus
