The design of sports energy expenditure measuring device based on three-dimensional motion sensor

Abstract

Abstract The effectiveness of the measurement method based on accelerometer for human sports energy expenditure has been confirmed by research in recent years. In this paper, combined with the overall design requirements of micropower consumption and miniaturization, this paper describes the design scheme of a portable measuring device that uses three-dimensional accelerometer to measure sports energy expenditure. The general design idea of the measuring device and the implementation method of main functional units are discussed in detail.
