| 摘要 |
The invention relates to a shielding film (40; 50; 60) comprising a plurality of superposed layers (41, 42, 43; 51, 52; 61, 62) for a device that has a system for cableless charging. Each layer (41, 42, 43; 51, 52; 61, 62) has a plurality of strips (44, 44', 44''; 53; 63, 64) of a nanocrystalline soft magnetic alloy arranged on an adhesive layer (45, 57, 65), and the nanocrystalline soft magnetic alloy has a circular hysteresis loop. The strips (44, 44', 44''; 53; 63, 64) in adjacent layers (41, 42, 43; 51, 52; 61, 62) are offset from each other. |
