Standard Finite Element (FE) models, especially those that incorporate multiple physical domains, consist of detailed representations of a device that include a large number of Degrees of Freedom (DoF ...

How do piezoelectric accelerometers — vibration sensors — work? The force caused by vibration or a change in motion (acceleration) causes the sensor's mass to “squeeze” contained piezoelectric ...

Anyone who has performed vibration tests is familiar with accelerometers, which are positioned on the EUT to measure the acceleration relative to the shaker and, most importantly, to find resonances.

One of the most critical decisions in developing random vibration tests also is the most neglected. The location of the control accelerometer is one of the most critical decisions when developing ...

LONDON — Motion sensing, largely enabled by Micro Electro-Mechanical Systems (MEMS) accelerometers, has taken more than its usual share of the headlines recently. Whilst not a rags to riches tale – ...

Researchers at the National Institute of Technology (NIST) have developed a new type of accelerometer based on lasers and optomechanical principles rather than the traditional mechanical strain gauges ...
