[0034] The preparation of the nano conductive rubber sensing unit of the present invention mainly adopts the solution blending method and compression molding, and the specific preparation method is as follows:
[0035] S1. Ingredients: Weigh the basic components of silicone rubber (PDMS), curing agent and carbon nanotubes according to the mass ratio, pour them into the mixer, and perform mechanical grinding and mixing at room temperature to ensure that the carbon nanotubes are in the rubber matrix. Evenly distributed in the medium to make a nano-conductive rubber solution.
[0036] S2. Synthesis: Prepare multiple high-strength fabrics of the same size, spread a fabric layer on the bottom plate of the mold, evenly coat the nano-conductive rubber solution prepared in S1 on the fabric to a certain thickness, and then spread another fabric layer on it. Fabric layer: According to the thickness of the nano conductive rubber sensing element, the process of coating the nano conductive...
