[0027] Examples:
[0028] The present invention is based on the structure diagram of the array nozzle electrospinning direct writing precision variable magnetic scale as Image 6 As shown, it includes a non-magnetic film substrate and a magnetic film. The magnetic film covers the non-magnetic film substrate and records magnetism on the magnetic film to make a magnetic scale.
[0029] The above-mentioned variable precision magnetic scale has a uniform elastic structure.
[0030] The non-magnetic film substrate and the magnetic film deposition material are the same, the deposition structure is the same, and the deposition distribution is uniform.
[0031] The above-mentioned non-magnetic film substrate is a non-magnetic film formed by orderly depositing a non-magnetic polymer through multi-jet electrospinning; the magnetic film is made of the same polymer mixed with hard magnetic material particles and then passed through the array nozzle near-field electrospinning. Write formation.
