According to an embodiment of the present invention, provided is a piezoelectric harvesting system comprising a piezoelectric element for generating electrical energy if the system is mounted in a vehicle to apply external force from the outside. The piezoelectric element can be selectively attached to an external surface, an internal surface, or a lower surface of a tire house covering a tire from the outside of the tire. According to the embodiment of the present invention, the piezoelectric harvesting system can generate electrical energy using the piezoelectric element vibrated by the external force generated during the running of a movement means such as electric vehicles, by mounting piezoelectric element with various shapes and an arrangement structure on at least one surface among the internal surface, the lower surface, or the external surface thereof. The piezoelectric harvesting system can extend the travel distance of the movement means by charging a battery with the generated electrical energy. |
