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 ...

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 ...

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 ...
