Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] The flexible pressure sensor of the present invention includes an elastic body and a fabric strain sensor attached to the outside of the elastic body. The elastic body is preferably a regular cylinder. A certain stretching performance can expand and contract with the deformation of the elastic body, so that the resistance change corresponding to the deformation can be generated by sensing the deformation of the elastic body, and output through the wire for detection.

Abstract

The invention relates to a flexible pressure sensor, a manufacturing method therefor, and a flexible pressure sensor array. The flexible pressure sensor comprises an elastic main body which is used for generating deformation according to external pressure; and a fabric strain sensor which is attached to the outer side of the elastic main body. The fabric strain sensor comprises a conductive coating layer which is disposed on a substrate layer in a coating manner and attached to the elastic main body in a close manner, and is used for sensing the deformation and correspondingly generating a resistance change according to the deformation; a knitted fabric substrate layer which is used for supporting the conductive coating layer; a flexible conductor which is connected with the conductive coating layer and is used for outputting the resistance change; and a protection layer which is disposed on the surface of the conductive coating layer in a coating manner, and is used for guaranteeing the uniform deformation of the conductive coating layer and reducing the sensing difference of all parts of the conductive coating layer.

Description

technical field [0001] The invention relates to the field of pressure sensing, more specifically, to a flexible pressure sensor sensitive to mechanical stress, a manufacturing method thereof and a flexible pressure sensing array. Background technique [0002] Pressure sensors have a wide range of applications, both in industry and in personal use. Various pressure sensing technologies such as potential detection sensors, inductive sensors, capacitive sensors, piezoelectric sensors, piezoresistive sensors, optical sensors, fluid sensors, and strain sensors have been greatly developed in various fields. However, these pressure sensors are generally large in size, high in hardness, and easy to be damaged, so the scope of application is small. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flexible pressure sensor and its manufacturing method and a flexible pressure sensing array for the defects of the above-ment...
