There are a number of ways to construct accelerometers, but the ones in the iPhone (and probably most other consumer-level equipment) specifically are MEMS accelerometers. As I understand it, a change ...

Have you ever wondered how your iPhone knows up from down, or when you’re shaking it? It’s all because of the tiny accelerometer chip inside the device, but how does it work? It’s not like the ...

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 ...

Researchers at the National Institute of Technology (NIST) have developed a new type of accelerometer based on lasers and optomechanical principles rather than the traditional mechanical strain gauges ...
