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 ...
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 ...
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 ...

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 ...
An alternative form of navigation is required for everything from navigating large vehicles to searching for dark matter in the far flung corners of space. Now, researchers at Imperial College London ...
