A cantilevered piezoelectric energy harvesting apparatus according to an embodiment of the present invention includes: a cantilevered energy generating part which is arranged in the first position of the outside of a moving body, and has a piezoelectric material; and a vortex generation part which is arranged in the second position of the outside of the moving body separated from the energy generation part, and periodically generates vortex shedding in the movement of the moving body. The first position is set in the back of the second position with respect to the moving direction of the moving body. The energy generation part receives vortex shedding generated by the vertex generation part and produces electric energy due to the deformation of the piezoelectric material at a resonance frequency. |
