PURPOSE: A piezoelectric harvesting system using compressive force is provided to prevent the overall loss of the piezoelectric by using compressive force out of external forces generated by the weight and hitting. CONSTITUTION: A piezoelectric harvesting system includes a piezoelectric (103), and a fixture (102). The piezoelectric is composed of piezoelectric materials. The fixture adheres to the piezoelectric. The piezoelectric adheres to one side where the fixture is compressed. The electric energy is produced by applying a compressive force to the piezoelectric when the compressive force is applied to the fixture. The fixture comprises a fixture support stand (107) and an extension protector (105). The fixture support stand is mounted in a cantilever type. When one region of the fixture in which the piezoelectric is not adhered is hit, the compressive force is applied from the fixture and the piezoelectric. The extension protector is adhered to the other side of the fixture, and prevents the fixture from being extended in the process of being restored after the fixture receives the compressive force. |
