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 ...

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 ...

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 ...

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 ...

What keeps the Internet of Things from becoming a tangled jumble of incoming data from various connected devices? And within a single device that feeds information into the IoT, how does sensor fusion ...

ST has integrated six accelerometers into a 2.5 x 3mm inertial measurement unit for sports wearables. “Capable of measuring events ranging from slight movements to intense impacts with equal accuracy, ...
