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 ...

Researchers at Georgia Tech and MIT have developed a proof of concept to demonstrate that it is possible to record a computer user’s keystrokes using an iPhone 4’s accelerometer. The researchers ...

This article discusses how to improve tilt measurement accuracy using an accelerometer like a combo part. Electric park brakes (EPBs) are used on passenger vehicles to hold the vehicle stationary on ...

Objective This systematic review assessed the completeness of accelerometer reporting in physical activity (PA) intervention studies and assessed factors related to accelerometer reporting. Design The ...

As any smartphone aficionado knows, the accelerometer is one of the key sensors within the device – it allows the phone to know when and by how much it’s been moved. Accelerometers also have many ...

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 ...

We barely notice them, but they're one of the most important features buried in the everyday smartphone experience. Accelerometers are devices that can measure acceleration (the rate of change in ...

MEMS inertial-sensors technology has been driven by automotive safety systems; as such, the technology has been applied to several high-volume applications. The large volumes associated with ...

Even if you’ve never attended a rave, you have probably seen one portrayed on film or television. Those glowing spheres-on-a-string being swung around are called poi, and [Matt Keeter] has designed a ...

Background In volleyball, training and match exposure is a risk factor for developing patellar tendinopathy which is known as jumper's knee. The frequency of jumping is an indicator of the intensity ...
