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 ...

Objective Although 30 min/day of moderate-intensity physical activity is suggested for preventing type 2 diabetes (T2D), the current recommendations exclusively rely on self-reports and rarely ...

One of the most difficult aspects of selecting an accelerometer for a particular application is interpreting the accelerometer’s specifications. Often you understand your test requirements well but ...

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 ...

On the smallest scales, our universe gets weird. Particles act like billiard balls or waves on water, depending how you probe them. Properties can't be measured simultaneously or tend to smear ...

Detects when an object is near to the phone. Most commonly used to sense when a phone is held up to the users ear to turn off the display. This saves both battery life and prevents accidental screen ...

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 ...
