In order to collect the vibration energy when cars through the road, a vibration generation device based on piezoelectric materials is designed to transform vibrational energy into electricity, collecting maximum vibration energy from the environment. For purpose of absorbing the maximum external energy, the following research is completed. The influence of the deformation of piezoelectric material to generate electricity is analyzed, and a model which can find the minimum deformation of piezoelectric materials to produce maximum electricity is designed. A hybrid circuit model mainly in parallel and secondly in series is made based on the analyzing of the influence of the link method of piezoelectric patches to the electrical energy output. A piezoelectric generation device is made and experiments show the power of electrical energy output is 0.061 2 W, capacitors store electrical power is 0.026 4 W, power generation efficiency is 14.42%, and capacity storage efficiency is 6.21%.
