In other embodiments, the conductive body 4 may be a conductive cloth, a conductive wire, a conductive film, or any conductive body 4. The intermediate layer 111 may be nylon yarn, foamed plastic, fiber, or the like. In addition, a housing cavity (not shown) is provided in the intermediate layer 111, and the housing cavity houses the flexible sensor 2 and is in interference fit, or the flexible sensor 2 and the skin layer 12 are integrally molded.
In an embodiment, with reference to fig. 3, the flexible sensor 2 of the present solution includes: a first silicone rubber layer 21, a metal layer 22 disposed on the first silicone rubber layer 21, and a second silicone rubber layer 23 covering the metal layer 22. Namely, the flexible sensor 2 is a three-layer structure, and the flexible sensor 2 is realized by magnetron sputtering. Specifically, the bottom layer is a first silica gel layer 21, then metal is sputtered in a magnetron sputtering manner to form a metal layer 22, the material of the metal layer 22 can be gold, silver, copper, iron or alloy, and the like, the thickness of the metal layer 22 is less than millimeters, and the thickness of a micron-scale or nanometer-scale is set according to the requirement of a product; finally, a second silica gel layer 23 is further disposed on the metal layer 22, so as to form the flexible sensor 2 with a three-dimensional structure.
