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 ...
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 ...
There’s a good chance that you use a MEMS accelerometer every single day. It’s the small chip that let your smart phone automatically adjust its screen orientation. They’re great chips, and since they ...
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 ...
Researchers at the California Institute of Technology (Caltech) and the University of Rochester have developed an ultrasensitive microsensor accelerometer. Their device uses laser light to gauge ...
