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 ...

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 ...

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 ...

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 ...

Objective Data on cardiovascular outcomes according to objectively measured physical activity (PA) in patients with atrial fibrillation (AF) are scarce. This study explored the associations between PA ...

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 ...

Everyone should probably know that I'm obsessed with both physics and smart phones. If I can use my phone for a physics experiment, I'm good to go. That's exactly what I am going to do right now—use ...

[Viktor’s] washing machine did a good job of cleaning his clothes, but it kept a bit too quiet about it. The machine doesn’t have an audible alert to let him know the cycle has finished. He decided to ...

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 ...
