Microelectromechanical coupled resonating arrays are being used for detecting biological and chemical analytes through mass sensing. Such arrays of perfectly identical resonators can be considered as periodic, ordered, non-localized systems. The change in the eigen parameters of the ... En savoir plus
Micro computation provides a special-purpose computing paradigm and is integrated on small-scale microfluidic platforms. Because of their very small size, fluidic computers have a number of advantages and potential. Fluidic computers works on fluids such as air, water etc. and does not ... En savoir plus
The objective of this paper is to show the simulation of a piezoelectric thin film device and its application as a sensor. Piezoelectric aluminum nitride thin film clamped at two ends is simulated using COMSOL Multiphysics software. The device consists of the piezoelectric thin film ... En savoir plus
PCR (Polymerase Chain Reaction) is a recent well researched technique which can be employed to obtain an amplified DNA (Deoxyribonucleic Acid). A continuous flow polymerase chain reaction with integrated MEMS based design micro heater for DNA amplification is implemented. Temperature ... En savoir plus
Micro heat sinks can be widely used for cooling in modern microelectronic high heat flux components where the amount of heat generated sometimes exceeds the limit which the system can withstand. Microstructures when introduced into the channels of heat sinks in form of micro fins enhance ... En savoir plus
In this paper simulation and parametric study of a PDMS valveless micropump using Fluid-Structure Interaction (FSI) appraoch is presented. The simulation for the valveless micropump were carried out in COMSOL Multiphysics software. In case of a valveless micropump diffuser/nozzle element ... En savoir plus
The paper presents finite element simulation of a surface acoustic wave (SAW) linear motor. The function of SAW linear motor depends on the principle of friction drive provided by SAW propagating on a piezoelectric substrate. The SAW motor comprises of a slider driven by Rayleigh wave ...

In this report, we present the design and analysis of microcantilevers of various shapes and materials for different applications. Here we investigate the sensitivity i.e. amount of bending of the cantilever due to same amount of force applied to each of the shape and the respective ... En savoir plus
Silicon based MEMS have wide applications in under water sensors. This work aims one such applications, hydrophone. Hydrophone detects the pressure variations of acoustic signals and noise in the water and produces an output voltage proportional to the pressure. Here the attempt is made ... En savoir plus
In this paper, a free membrane is used as a receiver to increase the capacitance and therefore the resolution of the flow meter. For the current application, from the wavelength of sound wave in soft tissue (c= 1540 m/s) the resolution was calculated to be 0.48 mm. This gives the first ... En savoir plus
