• The purpose of our research is to develop an energy harvesting device for a power-line magnetic field of 60 Hz. This device consists of an energy harvesting module and a power conditioning module. The harvesting module can provide 25 mW to an optimum load of 1 kΩ from a field of 45.3 μT. To use the harvested energy as a battery, a power conditioning module consisting of a rectifier circuit and a DC-DC converter is required. We prepared two fullwave rectifier circuits with different Schottky diodes, and an ultralow voltage step-up converter for an output of 5 V. The efficiency of the rectifier circuit was greater than 80 %. It was found that the efficiency of the DC-DC converter depended on the input voltage and the dummy load. From experiments, we successfully demonstrated that our developed harvesting device can provide an output voltage of 5 V. To use this device as a battery, loss in the power conditioning module was also discussed.
