Possibility of Magnetic Energy Harvesting for Zero-power Sensor

Abstract

This paper summarizes the possibility of magnetic energy harvesting for zero-power sensor. Magnetic energy harvesting has the advantages of both wireless power transmission and energy harvesting technologies. From the view point of solar power harvesting technology using photovoltaics, the motivation of magnetic energy harvesting technology is explained. The global trend of energy harvesting from magnetic field on the power management system is summarized. Towards the contribution to IoT technologies, the possibilities of zero-power sensor using magnetic field are also discussed.
