A configuration that shows great promise in sensing applications is vertically aligned piezoelectric nanowire arrays that allow facile interfacing with electrical interconnects. Nano-electromechanical ...

[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 ...

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 ...

Smartphones are pretty amazing when you think about it. Besides letting you watch Star Wars whenever you want, answer any question instantly, and play Super Mario Run during staff meetings, ...

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 ...

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 ...

Objective Self-reports of physical activity (PA) have been the mainstay of measurement in most non-communicable disease (NCD) surveillance systems. To these, other measures are added to summate to a ...
