Surface Acoustic Wave Based MEMS Resonator

S. Dixit[1], R. C. Jain[1]
[1]Jaypee Institute of Information Technology, Noida, Uttar Pradesh, India

Surface Acoustic Waves (SAW) is the acoustic wave that propagates along the surface of the substrate with amplitude decaying exponentially away from the surface. A basic SAW device consists of two IDT’s on a piezoelectric substrate such as quartz. Surface Acoustic Wave can be ... En savoir plus

A Microfluidic System for Capturing Malaria-Infected Blood-Cells Using an Array of Nickel Structures

Pachara Noosawad [1],
[1] Chulalongkorn University, Thailand

Treatment and prevention of malaria, a disease having an anopheles mosquito as a carrier, have become a severe medical issue to many countries in a tropical zone. It was reported that there have been patients about 300-500 millions all over the world[1]. Many countries in South East Asia ... En savoir plus

3D Numerical Simulation of Resistance Sintering for Electrical Contact Applications for Breakers

J. AMOVIN-ASSAGBA¹, V. BRUYERE², P. NAMY², C. DURAND¹, S. ROURE¹
¹SCHNEIDER ELECTRIC, 31 Rue Pierre Mendes France, EYBENS, FRANCE
²SIMTEC, 5 Rue Felix Poulat, GRENOBLE, FRANCE

In circuit breakers, short-circuit breaking involves extreme conditions linked to the presence of an intense electric arc. This requires the use of specific electrical contacts consisting of a contact tip and its support. SCHNEIDER ELECTRIC uses the resistance sintering technique for the ... En savoir plus
