The aim of this paper is to propose an energy harvesting system by converting mechanical energy of revolving door into electrical energy. The method of energy harvesting system is discussed on two methods: one is the energy-harvester using gear shaft coupling system, and the other is the energy-harvester using spiral spring system. The former is generated by coupling the shaft of rotating door with generator system, while the latter is generated by connecting end-effector of door with the string of generator system. We present the experimental results for two developed energy-harvester. Finally, a comparison between these results is presented to show the validity of energy-harvester.
