This study informs regarding application to electric protection by using piezoelectric material which is one of the energy harvesting system in bridge. It can transform from strain energy to electricity energy by using piezoelectric material as strain energy always occurs in bridge. This paper suggests that electricity energy occurred from piezoelectric material can use cathodic protection by power impressed methods for anti corrosion of reinforcement bar, steel and so on.
