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 ...

Industries and R&D sites depend on sensors to measure, monitor and analyze vibrations. Unfortunately, the best ways to get accurate and repeatable vibration data are not clear to many engineers; they ...

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 ...

Apple is looking to advance the design of its bundled iPhone EarPods by potentially implanting an accelerometer into the earbud portion that could recognize voice activity, which in turn would ...
