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 ...

MEMS (micro electromechanical system) inertial sensor technology provides a major structural shift in mechanical sensing. When the performance meets their needs, system developers welcome trading ...

There are a number of ways to construct accelerometers, but the ones in the iPhone (and probably most other consumer-level equipment) specifically are MEMS accelerometers. As I understand it, a change ...

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 ...
