The application relates to a bending degree detection unit, device, method, and wearable device, belonging to the field of electronic technology. The bending degree detection unit includes: a non-conductive flexible substrate; located on the flexible substrate and connected to the flexible substrate A first flexible conductive layer attached; and a second flexible conductive layer positioned on a portion of the first flexible conductive layer, the first end of the second flexible conductive layer is in contact with the first flexible conductive layer, the second end is in contact with the flexible lining Bottom contact; when the flexible substrate is not bent, there is a gap between the second flexible conductive layer and a part of the first flexible conductive layer; it can solve the inaccurate detection results obtained by the existing bending degree detection method and require the user to wear it next to the body The problem of the problem; the change of the contact area between the flexible conductive layers leads to the change of the resistance, and it is no longer necessary to wear an elastic structure that is close to the body. Once a certain area of the clothing is bent and deformed, the change of the resistance output signal can be obtained; at the same time, the detection can be improved. the accuracy of the results.
Description
Technical field [0001] The present application relates to a bending degree detecting unit, a device, method, and a wearable device, belonging to the field of electronic technology. Background technique [0002] At present, the curved sensor of the textile usually determines the degree of bending by the pressure change caused by the bending of the fabric; or uses a knitting method to woven the conductive fibers into the textile, using the elasticity of the knitted fibers to pull the conductive fibers, resulting in the change of the resistance, and further determine the fabric Bending degree. [0003] However, the method of detecting the degree of bending is not accurate, the degree of transverse / longitudinal bending is different, and the degree of bending is not accurate enough, and the user is required to be worn. Inventive content [0004] The present application provides a bending degree detecting unit, a device, method, and a wearable device that solves the detection result...
