Prognostics of Electronics under Vibration Using Acceleration Sensors

This paper discusses a prognostics methodology for assessing the remaining life of a group of electronic components mounted on a circuit board using a single accelerometer to monitor the life-cycle vibration loads. The accelerometer captures the global circuit board response to enable all components on the circuit board to be analyzed. A case study is presented using a single accelerometer moun...

“MEMS based seismic and vibration sensors in Building & Structural Health Monitoring systems”

Structural Health Monitoring systems are increasingly being installed throughout the world most especially in areas vulnerable to high levels of seismic activity but also within large structures subject to sub-surface landslip, mining, or externally induced stress and vibration. Strong Motion seismic sensor technology is evolving in respond to these emerging demands with traditional Electromech...

Vibration Analysis of MEMS Sensors for Detection of Ultrasound

The modal vibration characteristics of new MEMS (microelectromechanical systems) ultrasonic sensors have been studied theoretically and experimentally. Such studies are needed in order to design MEMS sensors with improved sensitivity for detection of ultrasound. The determination of vibration behavior of such sensors is critical for a successful design, and a validated vibration characterizatio...

Accurate Model of Capacitance for MEMS Sensors using Corrugated Diaphragm with Residual Stress

In this paper we present a new model for calculating the capacitance of MEMS sensor with corrugated diaphragm. In this work the effect of residual stress is considered on deflection of diaphragm and capacitance of sensor. First, a new analytical analyzes have been carried out to derive mathematic expressions for central deflection of corrugated diaphragm and its relationship with residual stres...
