The activPAL3c is a small (35 x 53 x 7mm), light weight electronic device, worn on the anterior mid-line of the right thigh, one third of the way between hip and knee. The activPAL3c uses a tri-axial accelerometer to sense limb position and acceleration, collecting information at a 20 or 100Hz sampling frequency on uni-axial or tri-axial modes. The activPAL™ software is used to classify an individual’s free-living activity into periods spent sitting, standing and walking.
