[1]National MEMS Design Center, Department of Applied Physics, Shri G S Institute of Technology & Science, Indore 452003 MP, India

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 ... Mehr lesen

Elucidating the Mechanism Governing the Cell Rotation Behavior Under DEP

G. Zhang[1], Y. Zhao[1], J. Brcka[2], J. Faguet[2], E. Lee[2]
[1]Clemson University, Clemson, SC, USA
[2]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

In our experiments with manipulating cells with DEP, we noted that some cells are constantly spining. By hypothesing that the cell spining is caused by the non-circular shape of the cell body and the off-centered location of its nucleus and that the rotation direction depends on the ... Mehr lesen

Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

G. Zhang[1], Y. Zhao[1]
[1]Clemson University, Clemson, SC, USA

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 ... Mehr lesen

Effect of Electrical Field Distortion on Particle-Particle Interaction Under DEP

[1]Clemson University, Clemson, SC, USA
[2]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

In using DEP for particle manipulation, researchers often use a formula to calculate the DEP forces in which the forces are proportional to the particle radius to the third power. This formula assumes that the electrical field, E, will not be affected by the presence of a particle, no ... Mehr lesen

Joule Heating in Electroosmotically Driven Circular Constriction Microchannel

U. Sanjay [1], P. Sarith[2], R. Ajith Kumar[1]
[1]Amrita Vishwa Vidhyapeetham, Kollam, Kerala, India.
[2]National institute of Technology, Calicut, Kerala, India.

Liquid transport in lab-on-a-chip (LOC) devices occurs through a microchannel that uses an electroosmotic flow actuation mechanism. This method has a plug-like velocity profile, which is ideal in species transport and in wall-bounded reactions. Under substantial joule heating, it is not ... Mehr lesen

Structural Durability Analysis of Powertrain Mounting Bracket

Sameer Kolte[1], David Neihguk[1], Abhinav Prasad[1]
[1]Mahindra and Mahindra Ltd., Vehicle Integration COE, Mahindra Research Valley, Mahindra World City, Chengalpattu, Tamil Nadu, India

Structural analysis is performed to check the durability of Engine mounts for a given load and support conditions. The engine mount bracket is subjected to loads primarily due to weight of the powertrain and the unbalanced torque. In this analysis, the component is optimized such that ... Mehr lesen

Simulation Studies on the Design of a Helmholtz Resonator type Underwater Acoustic Sensor

Karthi Pradeep[1], G. Suresh[2], V. Natarajan[2],
[1]National Institute of Technology, Tiruchirappalli, Kerala, India
[2]Naval Physical & Oceanographic Laboratory (NPOL), Kochi, Kerala, India

A Helmholtz resonator type acoustic sensor has been designed using analytical method and finite element modeling software, COMSOL Multiphysics®. The acoustic sensor is an aluminium double frustum, hour glass, shaped with the resonator at the bottom and an acoustic horn above to amplify ... Mehr lesen

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 ... Mehr lesen

Multiphysics Modelling and Simulation of Implantable Wireless MEMS Capacitive Sensor for Cardiovascular Diagnostics

R.Yogeswari[1], S.Venkateshwaran [1], K.Umapathi[1]
[1]United Institute of Technology,Coimbatore,Tamil Nadu, India

Monitoring the Central aorta is a more effective way to diagnose cardiovascular diseases than conventional techniques. Approximately, six million people in the world are currently living with aortic aneurysm and every year 750,000 new cases are diagnosed. This paper presents the design ... Mehr lesen

CFD Analysis of Ejectors

Vikas N Bhargav[1], Vivek Ganeshan[1], Muralidhara Holla[1], Ramesh Kolluru[1]
[1]Mechanical Engineering Department, BMS College of Engineering, Bangalore, India

Ejectors are the devices used to carry out mixing and recompression of two fluid streams, one with higher energy and the other with lower Energy. The high energy fluid is passed through the converging nozzle of ejector to very high velocities which in turn creates suction and draws the ... Mehr lesen
