Simulations of Micropumps Based on Tilted Flexible Structures new

M. J. Hancock[1], N. H. Elabbasi[1], M. C. Demirel[2]
[1]Veryst Engineering, LLC., Needham, MA, USA
[2]Pennsylvania State University, University Park, PA, USA

Pumping liquids at small scales is challenging because of the principle of reversibility: in a viscous regime, the flow streamlines through a fixed geometry are the same regardless of flow direction. Recently we developed a class of microfluidic pump designs based on tilted flexible ... En Savoir Plus

Design of High Performance Micromixer for Lab-On-Chip (LOC) Applications

K. Karthikeyan[1] , L. Sujatha[1]
[1]Rajalakshmi Engineering College, Chennai, Tamil Nadu, India

This paper presents the design and simulation of micromixer for Lab-On-Chip (LOC) applications. There are two types of micromixers: one is an active micromixer and another one is a passive micromixer. This paper investigates microfluidic flow characterization and mixing rate of two ...

Polymer Nanowire based Impedance Biosensor

N. Das[1], C. R. Chaudhuri[1]
[1]Department of Electronics and Telecommunication, BESUS, Howrah, West Bengal, India

In this paper, we have proposed an impedance biosensor based on polymer nanowire (made of polyaniline) for efficient electric field mediated capture of biomolecules. Existing polymer nanowire based biosensors fail to achieve high sensitivity for low surface to volume ratio as the whole ... En Savoir Plus

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 ... En Savoir Plus

FEM Correlation and Shock Analysis of a VNC MEMS Mirror Segment new

E. Aguayo[1], R. Lyon[2], M. Helmbrecht[3], S. Khomusi[1]
[1]The Newton Corporation, Bowie, MD, USA
[2]NASA Goddard Space Flight Center, Greenbelt, MD, USA
[3]Iris AO, Inc., Berkeley, CA, USA

Microelectromechanical systems (MEMS) are becoming more prevalent in today’s space technologies. The Visible Nulling Coronagraph (VNC) instrument, being developed at the NASA Goddard Space Flight Center, uses a MEMS Mirror to correct wavefront errors. This MEMS, the Multiple Mirror ...

The Simulation of Motion of a Slider upon a Stator Due to Frictional Force Using COMSOL Multiphysics® Software new

H. B. Nemade[1]
[1]Indian Institute of Technology Guwahati, Guwahati, Assam, India

The Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction ... En Savoir Plus

Push or Pull, How Does Silk Flow?

J. Sparkes [1],
[1] University of Sheffield, Sheffield, UK

Silk is one of the longest used and most recognizable textiles that we, as a society, use regularly. We see it as a luxury good, worn as an indicator of success and value. However, despite mankind having domesticated and farmed silkworms for millennia, we still know relatively little ... En Savoir Plus

Optimization of Device Geometry of a Fully-Implantable Hearing Aid Microphone

A. Dwivedi [1], G. Khanna [1],
[1] National Institute of Technology Hamirpur, Himachal Pradesh, India

The hearing impairment is affecting more than 360 million people all over the world.In India alone, 63 million people suffer from the significant auditory loss. Conventional hearing aids suffer from reliability, practicality and social stigma concerns. The totally implantable devices ... En Savoir Plus

Rough Surface Modeling of PDMS Polymer through Fractal Dimensions

D. Altuve [1], G. Fernandez [1], L. Paredes [2],
[1] Circuits and Electronics Department, Universidad Simón Bolívar, Caracas, Miranda, Venezuela
[2] Faculty of Electronic and Biomedical Engineering, Universidad Antonio Nariño, Tunja, Colombia

A good approximation of rough surfaces and their random behaviour is very important in some engineering problems. Fractal modelling provide an alternative to generate rough surfaces based in statistically self-similar non-Euclidean geometries, as seen in [Fig. 1]. Through a frequency ... En Savoir Plus
