PURPOSE: A piezoelectric harvesting system using water stream is provided to improve the efficiency of generating energy because a piezoelectric element is made of hybrid and polymer materials. CONSTITUTION: A piezoelectric harvesting system(100) using water stream comprises a movable body(101) and a piezoelectric element(110). The movable body is vibrated by external power. The piezoelectric element is formed in the movable body, and generates electric energy. The piezoelectric element is mounted on the outer surface of the movable body. The movable body is formed into a fish shape, and includes a head portion(120) and a body portion(121) connected to the rear part of the head portion. The head portion includes a vibration part which amplifies the shaking of the body and head portions in proportion to the strength of water stream. |
