Dosing a predetermined quantity of one liquid into another, in a controlled fashion, is a process often encountered in a variety of operations at both industrial and laboratory scales. This process becomes a challenging one if it has to be carried out in a continuous mode, without using ... En savoir plus
The objective of this work is to develop a MEMS based Variometer to measure the vertical speed and to sense the instantaneous rate of climb or descent in Aircrafts to meet the miniaturization requirements in avionics industry. The design consists of dielectric material in between two ... En savoir plus
The primary function of the vestibular system is to provide the brain with information about the body\'s motion and orientation. The absence of this information causes blurred vision and spatial disorientation, vertigo, dizziness, imbalance, nausea, vomiting, and other symptoms often ... En savoir plus
The biological hair-cell is a modular building block of a rich variety of biological sensors. These sensors are responsive to various mechanical properties like vibration, touch, gravitational forces, etc., especially flow. Using micro and nano-fabrication technology, an engineering ...

In this work, we present the performance analysis of novel micro machined Piezoresistive fluid flow pressure sensor using COMSOL Multiphysics. The principle of the sensing mechanism is based on the deflection of four sensing layers embedded on a thin membrane. The fluid passes through ... En savoir plus
This paper will describe the dependence of capacitive accelerometer characteristics on the accelerometers physical dimension and its material properties. The sense element of the accelerometer is designed on the basis of a commercially available torsion based accelerometer technology. ... En savoir plus
In this work, a MEMS based condenser microphone [1,2] using Polyimide as the diaphragm has been designed. The microphone structure has a backplate placed on top of the diaphragm. The backplate and the diaphragm are made up of polyimide. The two polyimide plates are separated by air gap ... En savoir plus
In Pressurised Heavy Water Reactors (PHWRs), the fuel bundles are located inside horizontal pressure tubes made of Zr 2.5 wt% Nb alloy. During reactor operation, pressure tubes undergo corrosion reaction with the heavy water coolant flowing through it and picks up a part of the hydrogen ... En savoir plus
