PURPOSE: A moving body application piezoelectricity harvesting system is provided to hit a piezoelectric element by rotating a rotation module for a piezoelectricity module in proportion to the intensity of fluid such as wind and to increase generated energy of electric power. CONSTITUTION: A piezoelectricity harvesting system (100) comprises: a piezoelectricity module which comprises a piezoelectric element and is arranged in a gateway formation space (105) of a railway in which an entrance (106) and an exit (107) of wind is formed in order to insert the wind in a constant direction and discharge it; a rotation module (150) which is formed in the gateway formation space in order to surround the piezoelectricity module and hits the piezoelectric element of the piezoelectricity module by the wind. |
