N2 - A cloth-structured magnetic device was designed, and the optimized relation between amorphous fiber and conductive fiber size was shown. The inductance, equivalent resistance, and quality factor of cloth-structured magnetic devices were calculated. Furthermore, the stray capacitance of the device was estimated from the analysis of an equivalent circuit. A cloth inductor of only 0.7 mm thickness could be made, which could have an inductance of 100 μH, a rating current of 100 mA, and a quality factor over 60. Regarding the further miniaturization of the device, the magnetic flux distribution established inside the cloth inductor was measured. The miniaturization limit was estimated, which was influenced by the magnetic permeability and the aspect ratio of the fibers.
