Short summary
In this paper, we propose a piezoelectric energy harvester for human body motion. Based on an analysis of dynamics equations, we find that such a piezoelectric energy harvester performs very well, especially at lower frequencies. We suggest that the piezoelectric beam of an energy harvester subjected to multi-excitation with different modes of motion is quite suitable for harvesting energy from human body motions.
