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 ...

IMUs (inertial measurement units) have expanded from their traditional military usage and are now finding wider application in industrial segments. With their more compact form factors, lower power ...

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.

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 ...
