Title:
PLANAR COIL ARRAY AND DISPLACEMENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2024/013825
Kind Code:
A1
Abstract:
Provided is a three-dimensionally shaped coil that can be manufactured at low cost and easily and that uses a planar coil array. In a planar coil array (AR), a flexible board (321) comprises: a first planar coil (SU1) that has a first spiral shape in which a first conductor is wound in a left-handed or right-handed manner with respect to a first center; and a second planar coil (SU2) in which a second conductor in the same layer as the first conductor formed on the flexible board (321) is wound with respect to a second center in the same manner of winding as the first coil, the second planar coil having an angular misalignment from the first spiral shape, being disposed adjacent to the first planar coil in a predetermined direction, and being electrically connected to the first planar coil. The flexible board (321) is bent, thereby forming a three-dimensionally shaped coil.
