Vibration-induced energy harvesting for green technology

Abstract

A basic experimental study for the development of a power generation system using the vibration energy of urban infrastructure, such as railroads, highways, and bridges, was carried out to harvest electricity from moving vehicles. Starting with the proposal of a vibration power generator which converts vibration energy into electric power using self-induction technology, the research explains the basic concept of self-induction technology and the dynamic characteristics of a vibration power generator. Also, in order to analyze the correlation of an electromotive force from a vibration power generator which depends on an external force and vibration speeds, many indoor experiments with various variables were performed. Based on the experimental results, the capability of a vibration power generator system was analyzed. With those results, the use of a vibration power generator system to acquire the maximum available power was confirmed.
