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 vehicles, an array of polymer MEMS pressure sensors have been developed that can transduce underwater pressure ...

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 ...

Design and Simulation of MEMS-based Sensor for Artificial Hand

P. Prema[1], Sakthivishnu.R[1], Sowmya. R[1], Chandra Devi K[1], Meenakshi Sundaram. N[1]
[1]PSG College of Technology, Coimbatore, Tamil Nadu, India

An artificial hand is the one that replaces the hand lost through trauma, disease, or congenital conditions. The proposed design is to simulate a sensor, used in prosthetic hand so as to measure the pressure required to hold the object, using COMSOL Multiphysics®. The physical parameters such as size, shape and mass of the object were optimized so as to hold an object. The weight of the object ...

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 ...

Tunable MEMS Capacitor for mm and μm Wave Generation

Arpita Das[1], Amrita Nandy[1], Sakuntala Mahapatra[1], Sk. Mohammed Ali[1], Minu samantary[1]
[1]National MEMS design centre ,Department of Electronics and Telecommunication, Trident Academy of Technology, Biju Pattnaik University of Technology , India

This paper demonstrates the design of a tunable MEMS capacitor with two plates (one movable and one fixed). The response time obtained is 5μs. The tunable capacitor plays an important role in RF circuits. We focus on a tunable capacitor simulated using COMSOL Multiphysics®. In an electrostatically tunable parallel plate capacitor, you can modify the distance between the two plates when the ...
