Activity-related energy expenditure (AEE) might be an important factor in the etiology of chronic diseases. However, measurement of free-living AEE is usually not feasible in large-scale ...
In part one of this series, we reviewed the internal structure of a 3-axis high precision MEMS accelerometer. In this second article, we will review how to acquire a good starting dataset to establish ...
Awide variety of accelerometers has been developed for measuring vibration, shock, and inertial motion. To reduce risk and ensure that meaningful and accurate data is collected, you must understand ...
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 ...
Most of the latest 3-axis digital-MEMS accelerometers on the market can generate interrupts for a number of applications. Some of the applications—such as screen rotation, wakeup, freefall, single ...
Security researchers have tracked commuters with over 90 percent accuracy through accelerometer data stolen from Android smartphones. In a paper describing the research, titled "We Can Track You If ...
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 ...
