Abstract

Energy harvesting from human foot motion is attractive for the electrical power source of wearable sensors. For human foot motion, three types of energies are available: bending in the sole, heel strike and swing motion. In this study, the magnitudes of these energies were analyzed by dynamic measurements using various sensors. Then, appropriate piezoelectrics and device structure for the energy harvesting were discussed for each energy. From these results, it was concluded that utilizing bending in the sole and organic piezoelectrics such as PVDF is the best way for the energy harvesting from walking.
