Consideration of Array Module Design for Energy Harvesting of Power-Line Magnetic Noise

Abstract:

Article Preview

Energy harvesting is a key technology for small self-sufficient devices, which use environmental energy as a source. If these devices target a wireless sensor network, their required energy is only a few mW. In our previous report, we demonstrated the ability to harvest 6.32 mW from a magnetic field of 21.2 μT at 60 Hz. This paper considers an array module design for power line magnetic noise energy harvesting. The experimental results show that small distance in axial direction makes the harvesting energy small. In order to investigate this phenomenon, magnetic flux distributions around the modules are also measured. From the results, we concluded that the modules should be separated by one diameter distance of the coil.
