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 ...

Bosch has included ±28g accelerometers in its latest 3D inertial measurement unit, aimed at sports wearables. Called BHI385, it also includes a 32bit processor running embedded AI software “creating a ...

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 ...

Motion sensing is a key ingredient in the portable designs built around augmented reality (AR) and virtual reality (VR) applications. But while motion sensors are bridging the real and virtual worlds, ...
