A Portable Measuring Instrument for Assessing Physical Activity Based on Triaxial Accelerometer

摘要

The usefulness of accelerometer for assessing physical activity has been widely accepted in recent years. In this paper, a portable measuring instrument based on triaxial accelerometer was presented, also the overall design scheme of the portable measuring instrument was expounded emphatically, and combined with the principles of low-power design and miniaturization design, the realization method of system design, signal conditioning unit and software design in the whole system was illustrated in detail.
