Multi-Dimensional Vibration Energy Harvester For Efficient Use In Common Environment
2015 IEEE SENSORS(2015)
Abstract
This study proposes a novel type of energy harvester for more effective harvesting of multi-dimensional vibration existing in common environment such as car, bicycle, human movements, etc. The proposed harvester has multi-dimensionally triggered vibrating components in a toroidal electromagnetic coupling structure. We designed and implemented a prototype harvester and compared its output characteristic with conventional cylindrical electromagnetic harvester under three different angle conditions which correspond to three orthogonal axes of multi-dimensional vibration. The results show that the proposed doughnut-shaped energy harvester operate under more broad range of vibration angle than conventional cylindrical counterpart where. Further study will focus on the improvement of output performance and availability of the proposed harvester in common environment beyond laboratory conditions.
