Also known as inertial sensors, accelerometers are critical elements in key applications such as automotive air-bag deployment, smartphone motion tracking, and industrial predictive maintenance. These ...
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 ...
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 ...
An optomechanical accelerometer that uses light to measure acceleration. Credit: F Zhou/NIST An accelerometer that uses laser light instead of just mechanical strain can register changes as small as ...
On the smallest scales, our universe gets weird. Particles act like billiard balls or waves on water, depending how you probe them. Properties can't be measured simultaneously or tend to smear ...
Quantifying the vibration of industrial machinery and using that information for condition monitoring (CM) has long been an ambitious goal, but also one with significant technical and implementation ...
The accurate identification of locomotion states from wearable sensor data using machine learning relies heavily on carefully selecting algorithm parameters, which remains a challenging task. This ...
