Piezoelectric materials are held wide attention for they introduce a renewable and convenient method on vibration energy harvesting technology. Many kinds of piezoelectric materials are investigated in the past few years. Different properties of the materials are discussed on the influences of power output. In this paper, a novel harvester are proposed to research the performance of different general piezoelectric materials. With vertically staggered rectangle-though-holes (VS-RTH) combined with the cantilevered energy harvester, modal and harmonic response analyses are simulated to test the properties of the materials. For further experimental preparation, fabrication of the material layers are introduced in detail. In addition, the charges generation mechanism is shown in the aspects of piezoelectric effect, mode and polarization. The paper lists parameters for general piezoelectric materials properties. Besides, it provides the vibration performance under different piezoelectric materials condition. Therefore, it could benefit further applications and selections of energy harvesting materials.
