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 ...

Accelerometers are increasingly ubiquitous in consumer devices and industrial applications, largely as a result of the advances in MEMS manufacturing techniques that have allowed the sensors to become ...

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 ...

“Microelectromechanical systems (MEMS) technology such as accelerometers for measuring acceleration and gyroscopes for measuring angular velocity have been implemented within several related devices ...
