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

This paper concentrates on developing a self-contained cochlea whose performance is at par with natural hearing. The Artificial Basilar Membrane (ABM) design is done in such a manner so as to get a performance similar to the natural hearing. Finite element analysis was done with the help ... En savoir plus

Voltage sensors are increasingly used for monitoring and load flow distribution. These sensors are safer, lighter in weight and lower in cost as compared to the conventional voltage transformers. The principal component of these sensors is high voltage resistors. The resistors have a ... En savoir plus

Piezo buzzers, made of piezoelectric material glued on a brass plate, are usually used as signaler, but the buzzer can also be used to convert mechanical into electrical energy. If acceleration influences the buzzer, the structure is bent by its mass and a voltage can be measured between ... En savoir plus

Real-time microstructure monitoring is important during the cooling process for hot-rolled strip steel production, as the microstructure formed determines the mechanical properties required by customers. The materials magnetic and electric properties, relative permeability and ... En savoir plus

Impedance spectroscopy is an established sensing methodology used in microfluidic flow cytometry systems to electrically measure cell characteristics. The fluid transport method used in most flow cytometers is continuous flow driven by external syringe or pressure regulated pumps. An on ... En savoir plus

Understanding and controlling moisture migration is paramount in the pharmaceutical industry to ensure the quality, safety, and efficacy of drug products across their entire lifecycle, from raw material receipt to final product distribution. Uncontrolled moisture migration can lead to ... En savoir plus

The growing adoption of electric vehicles has led to increased exposure of cars to stray magnetic fields. To address this issue, inductive position sensors have emerged as a viable solution due to their inherent immunity to stray magnetic fields. Widespread adoption of the inductive ... En savoir plus

This paper studies the application of laminate magnetoelectric (ME) material in displacement sensor. We studied the L-L block composite thanks to designed structure by coupling displacement signal with the displacement potential of ME composite. A nonlinear approximation is adapted to ...

In this paper, a carbon dioxide sensor is introduced. At present many CO2 sensors are available, but they all required power in the order of few watts, therefore they are not suitable for long term unattended operation. This paper gives the brief description of CO2 sensor modeling using ... En savoir plus
