A novel rectangle cymbal shaped piezoelectric energy harvester is proposed for harvesting vibration energy from asphalt pavement. The harvester is composed of a rectangle ceramic and two rectangle cymbal shaped caps which are attached to each surface of the ceramic. If pressures are given at both tops of the caps, the pressures are changed to tensions on the ceramic through a form change of the caps and the piezoelectric effect occurs at the ceramic to generate electricity. The finite element model of the single harvester is established. The output voltage of the harvester with buried depth of 40 mm is analyzed. The results show that the electric voltage of the single harvester is about 21.355 V. The effects of structure parameters on the electricity generating capability are analyzed and the results give help for the design of the harvester. For accomplishing the goal of harvesting energy in a large scale，two rectangle cymbal harvesters array are proposed, one is vertical and another is horizontal. The finite element method is adopted to analyze the stress electricity characteristics of the two rectangle cymbal harvesters arrays. The output voltages of the two harvesters arrays are all higher than that of the single harvester in series.
