Also known as inertial sensors, accelerometers are critical elements in key applications such as automotive air-bag deployment, smartphone motion tracking, and industrial predictive maintenance. These ...

A guide for engineers balancing performance, reliability, and manufacturability across today’s smart systems By Barry Brents, ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. When you use a compass app on your smartphone, it somehow knows which direction the phone is ...

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 iPhone detects movement and tilting of the handset through its built-in accelerometers. These devices are able to detect movement in six different directions and relay that information to games ...

In all but the most pedestrian of cases, you really should consider some form of input protection between your sensors and your computational platform. In my “Beginner’s Guide to Sensor Interfacing ...

Addressing stylish and minimalistic wearables, these next-generation accelerometers provide speech processing and voice enhancement among other functions. An accelerometer with an advanced feature set ...

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 ...
