Accelerometer-based determination of body posture and the timing of rest vs. activity. Data are from a study of the northern tamandua anteater Tamandua mexicana[21]. Acceleration was sampled at 19 Hz for ~3 seconds every 2 min. For simplicity, the y-axis is not shown and waveforms represent the average voltage measured every 2 min for each axis.
