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 ...

Accelerometers turn motion into measurable signals. From tilt and vibration to g-forces, they underpin countless designs. In this “Fun with Fundamentals” entry, we demystify their operation and take a ...

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 ...
