Title:
COUPLED PLANAR COIL, DISPLACEMENT SENSOR AND WEARABLE ELECTRONIC PRODUCT
Document Type and Number:
WIPO Patent Application WO/2021/179975
Kind Code:
A1
Abstract:
Provided are a coupled planar coil, a displacement sensor and a wearable electronic product, which relate to the technical field of induction coils. The coupled planar coil comprises a first fabric substrate, a second fabric substrate, a first inductance coil and a second inductance coil, wherein each of the first inductance coil and the second inductance coil comprises a plurality of turns of surrounding conductive fibers; the first inductance coil is arranged on the first fabric substrate; the second inductance coil is arranged on the second fabric substrate; and the first inductance coil and the second inductance coil are arranged in a stacked mode. The first inductance coil and the second inductance coil are both made of the conductive fibers and are arranged on different fabric substrates, respectively. This structure can not only realize the function of coupling planar coils, but can also reduce the size of the coupled planar coil and increase the flexibility of the coupled planar coil, and is more suitable for wearable electronic products.
