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 ...

The sensors in your smart device are a big part of what make it, well, smart. Sensors allow our devices to understand context— they tell phones where they are in space and how we’re using them. This ...

The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones. The "spooky action at a ...

Fiber Bragg grating (FBG) accelerometers and vibration sensors represent a rapidly evolving field with significant implications for structural health monitoring, seismic detection, and industrial ...

In an ongoing quest to bring you news about the guts of your next gadgets, here’s some riveting stuff about accelerometers. Remember when they first burst onto the scene? How much fun we had tilting ...

On the smallest scales, our universe gets weird. Particles act like billiard balls or waves on water, depending how you probe them. Properties can't be measured simultaneously or tend to smear ...

Phone sensor calibration improves smartphone accuracy and fixes common sensor issues. Learn methods, tips, and advanced steps ...

For years, accelerometers have been the workhorses of motion sensing in automotive systems. But as Adabala explains, they’ve reached a limit. “Accelerometers are good at detecting movement, but ...
