The purpose of this study is the application of bistable magnetic device (BMD) to magnetic energy harvesting (MEH). This paper presents the new large-diameter BMD for the application to energy harvesting. To improve the BMD output characteristics, multiple twists were applied to the FeCoV wire with a diameter of 1 mm. As a result, it was confirmed that the applying twists reduced the pulse-induced magnetic field and increased the output peak voltage. In addition, the prototype MEH-device using this BMD was able to generate approximately 5 mW of DC power in the magnetic field of 10 mT.
