Embodiment Construction
[0031] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] Such as Figure 1-6 As shown, a plurality of coils 1 with the same size and the same parameters can be used as attached figure 1 Arranged in the manner shown to form an array, polyimide is used as the base material, and the coil 1 is a flat coil, which is fabricated on the flexible circuit board 2 by means of a printed circuit, and the manufactured one has high reliability and good flexibility printed circuit. In order to improve the detection sensitivity of the coil 1 and reduce the mutual influence between the coils 1, the center of the coil 1 is embedded in the magnetic core 4, and its structure is as follows figure 2 As shown, the magnetic core is made of iron-based amorphous alloy with high magnetic permeability, and the two coil terminals 5 of the coil 1 are welded on the flexible circuit board 2, so that the coil 1 has the char...
