What is accelerometer data processing?

Accelerometers are wearable devices that measure accelerations of the body segment to which the monitor is attached. The signal is usually filtered and pre-processed by the monitor to obtain activity counts, i.e., accelerations due to body movement.

What is accelerometer signal?

An accelerometer is a device that measures the vibration, or acceleration of motion of a structure. The force caused by vibration or a change in motion (acceleration) causes the mass to "squeeze" the piezoelectric material which produces an electrical charge that is proportional to the force exerted upon it.

What is an accelerometer used for?

Accelerometers are sensing devices that measure a moving object's acceleration and can detect frequency and intensity of human movement [7].

Is accelerometer digital or analog?

Analog Devices accelerometers and iSensor® MEMS accelerometer subsystems provide accurate detection while measuring acceleration, tilt, shock, and vibration in performance driven application.
