Magnetic Barkhausen noise (MBN) is an emerging field in non-destructive testing, which utilizes the electromagnetic signals generated by small abrupt changes in magnetic field in a sample undergoing magnetization by an applied external magnetic field. These small ... En savoir plus
CT and MRI are current techniques used for stroke detection. Although they are favored for their high accuracy and resolution, there are many situations that a potable and low-cost imaging technique is required. Ultra-sound technique is portable, but it cannot be used for stroke ... En savoir plus
Acoustic landmine detection is accomplished using a loud speaker as an airborne source to generate low-frequency waves that enter the soil at a certain incident angle. At a specific frequency, the landmine will "vibrate" at resonance, imparting a certain velocity on the soil particles ... En savoir plus
This literature reviews the simulation of specific oxide coated MEMS based gas sensor analysis with various parameters such as power consumption, temperature uniformity, resistance change, sensitivity and selectivity etc. The property of the sensing layer of the device to change its ...

Volatile Organic Compounds (VOC) are a wide range of carbon based organic chemical compounds which evaporate easily at room temperature referred as volatile in nature. Human exhaled breathe consists of carbon dioxide (CO2) along with more than 3000 Volatile Organic Compounds exists like ... En savoir plus
In the humanitarian demining setting, it is crucial to detect landmines with reliable sensing performance. As Nuclear Quadrupole Resonance (NQR) is an effective method for detecting explosive materials, our group is currently developing the world’s first low-cost system for anti-vehicle ... En savoir plus
The objective of this simulation model is to enhance the thermal behavior in a MEMS Gas-Chromatographer (GC) pre-concentrator for Volatile Organic Compounds (VOCs) carried by Helium gas. The simulation plays a critical role in estimating voltages, thermal time constants, and spatial ... En savoir plus
As the ultrasonic sensor industry evolves towards lower costs, miniaturization, higher integration, and superior performance, Microelectromechanical Systems (MEMS)-based ultrasonic transducers have emerged as a prominent trend. This article introduces a Piezoelectric Micromachined ... En savoir plus
