MEMS Based Sensor for Blood Group Investigation

M. Kaushik [1], S. Katti [1], V. Saradesai [1], P. Naragund [1], P. Vidhyashree [1], A. K. V. Nandi [1]
[1] B.V. Bhoomaraddi College of Engineering and Technology, Hubli, India

This article describes the design of MEMS based cantilever structure intended for determination of blood group and it is compared with manual method. Cantilever structure design has a sensing layer and when a blood sample comes in contact with this, results in coagulation. The surface ... Read More

Low Cost All Optical Swept Source for Optical Communication Applications

J. T. Andrews[1], S. Chaurasiya[1], O. P. Chaudhary[1], D. Agarwal[1]
[1]National MEMS Design, Department of Applied Physics, Shri G S Institute of Technology & Science, Indore Madhya Pradesh, India

By introducing a periodic modulation in a waveguide, it is possible to create an interaction between forward-traveling and backward-traveling modes of an optical waveguide. Bragg grating may be a one dimensional diffraction grating which diffracts light from the forward-traveling mode ... Read More

Ultrasound Pressure Field of a Resonating Piezoelectric Membrane with Three Excitation Electrodes

V. Tzanov [1], E. Ledesma [1], F. Torres [1], N. Barniol [1],
[1] Universitat Autonoma de Barcelona, Spain

Micromachined ultrasound transducers can work as a sensor or actuator for measuring fluid speed and direction, mixing and exciting particles (sonication), taking images (ultrasonography), non-destructive testing and many other purposes in various fields. In this work, a COMSOL ... Read More

Using High Pressure Chemical Vapor Deposition to Make Multimaterial Optical Fibers

S. Chaudhuri [1], J. V. Badding [1],
[1] Pennsylvania State University, University Park, PA, USA

Ever since its advent optical fibers have revolutionized the communication technology but apart from communication they are being used in a variety of other areas such as medical technology, sensing, laser sources in the form of fiber lasers, amplifiers, cutting and drilling, defense ... Read More

Ultrafast Effects in 3D Metamaterials

N. Katte [1], P. Evans [2],
[1] Wilberforce University, Wilberforce, OH, USA
[2] Oak Ridge National Laboratory, Oak Ridge, TN, USA

The extraordinary electromagnetic response of nanostructured material, usually made up of a metallic structures distributed in within a dielectric matrix has attracted a lot of interest in recent years. These materials are technically called metamaterial (MM) since they possess ... Read More

Modeling the Sound Radiation by Loudspeaker Cabinets

M. Cobianchi[1], M. Rousseau[1]
[1] B&W Group Ltd, Steyning, UK

While musical instruments often rely on a body which resonates on purposefully to amplify the vibration produced by a string or a membrane, such as in a violin or a guitar, loudspeaker cabinets should not contribute at all to the total sound radiation, but aim instead to be a perfectly ...

Liquid Microlenses with Adjustable Focusing and Beam Steering For Single Cell Optogenetics

S. Berry [1], S. Redmond [1], P. Robinson [1], T. Thorsen [1], M. Rothschild [1], E. S. Boyden [2, 3]
[1] Massachusetts Institute of Technology - Lincoln Laboratory, Lexington, MA, USA
[2] Department of Biological Engineering, Massachusetts Institute of Technology, Cambridge, MA, USA
[3] Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge, MA, USA

In optogenetics research it is highly desirable to have a method that can deliver light and excite individual neurons in the brain in a controllable and single cell manner. Working toward this goal, we are developing liquid microlenses with active electronics that enable both focusing ... Read More

From Music to Non-Invasive Therapies via COMSOL Multiphysics® Models

E. Lacatus[1], G. C. Alecu[2], A. Tudor[2], M. A. Sopronyi[3]
[1]Polytechnic University of Bucharest, Bucharest, Romania
[2]Student-Polytechnic University of Bucharest, Bucharest, Romania
[3]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be ... Read More
