Energy Collection and Measurement of Power of the Movement of the Human Body

ABSTRACT

In this paper, a scheme for the collection of potential energy from the movement of the human body has been presented. According to the analysis of the movement characteristics of the body parts, an energy conversion mechanism was designed to adapt to the characteristics of human body movement. According to the characteristics of output energy conversion mechanism, an energy collection circuit was designed to convert the weak pulse energy storage output using a body energy conversion mechanism to provide a stable energy source for low-power-consumption sensors. The experimental results showed the energy conversion efficiency of the energy collection system proposed in this paper to be 42%. It was able to collect about 2 mW of human lower legs motion energy, which can meet the daily needs of low-power sensors mounted on the human body.
