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 ...

Actually, I've done this experiment before (although with an iPod touch). Of course, it's a fun experiment so it seems worthwhile to repeat the measurement. Of course most smart phones have some type ...

The ability to measure, monitor, and analyze vibration is essential to many industries and areas of research & development. Unfortunately, the proper methods for creating an accurate and repeatable ...

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 ...

In today’s fast growing drone market segment, sensor technologies are often the unheralded secret sauce inside. In this article, we discuss the current state of drones and the sensor technology that ...
