Many researchers have studied the harvesting from discarded energy such as solar energy, wind and vibration because of the exhaustion of fossil fuel and the environmental pollution. Particularly, vibration-based energy harvesting has increasingly received an attention in last decade. Therefore, the aim of study is to analyze the characteristics of piezoelectric materials to be used in the energy conversion system on vehicle road. At first, the dynamic loads of vehicle on the road are measured with respect to the weight and speed prior to analyzing the characteristics of piezoelectric materials. Then, the energy conversion amount of piezoelectric element is quantified for its size and type under the load profiles. The vehicle dynamic load is the average of 200kgf. The result indicates that the dynamic vehicle load is less affected by the speed. The generated voltage is 1.8kV, and extracted energy is 0.11mJ from one under the load of 8kgf applied on piezoelectric element. The power extracted from one passenger vehicle is able to operate a sensor and transmit acquisition data.
