With recent advanced in portable electric devices, wireless sensor, MEMS and bio-Mechanics device, the new typed power supply, not conventional battery but self-powered energy source is needed. Particularly, the system that harvests from their environments are interests for use in self powered devices. For very low powered devices, environmental energy may be enough to use power source. Therefore, in other to made piezoelectric energy harvesting device. The made 31type triple-morph cantilever was resulted from the conditions of 100㏀, 0.25g, 154㎐ respectively. The thick film was prepared at the condition of 6.57Vrms, and its power was 432.31㎼ and its thickness was 50㎛. And than, the fabricated piezoelectric cantilever was packaged for application.
