This study conducted a basic experiment to build vibration power generation system that has no limit of location to install, has consistent generation all the time regardless of weather changes, and forecast power supply. The vibration power generation system applies vibration energy occurring from cars driving on the bridge to infrastructure facilities by using Faraday's law and changing into electric energy. As a basic experiment study to build the vibration power generation system infra, this study suggested a non-powered self-generator and analyzed a relationship with electromotive force of vibration energy and the vibration generator through analysis of dynamic characteristics of the vibration generator and the interior experiment in order to lead and verify the formula generating electromotive force.
