     The thickness of the first polymer material  12  can be controlled by changing the thickness of the edge of the template. 
     The method for coating of the polymer material is a scrape coating method, through which an uncrosslinked layer of the polymer material with a flat surface and a uniform thickness can be obtained. 
     The liquid uncrosslinked layer  12  of the first polymer material is a polymer material that has not been cured and crosslinked. 
     The bubble treatment is to process the uncrosslinked layer  12  of the first polymer material through a vacuum device until there is no bubble. 
     The semi-crosslinked layer  12  of the first polymer material is a semi-crosslinked material between the liquid uncrosslinked layer of the polymer without curing and crosslinking treatment and the crosslinked layer  12  of the first polymer after fully curing and film forming. 
     The fabric composite component  3 , the first friction component  1 , and the integration of the first friction component land the flat fabric composite component  3 is all formed by chemical cross-linking of the first polymer material  12 and the second polymer material  32 . 
     According to the present invention, in the above—embodiment, a high-molecular polymer with high tear resistance and strong flexibility, such as silicone, is used as the second polymer material  32 . 
     The second friction component  2  is a conductive yarn or high-molecular polymer material with electropositivity and surface insulation, including but not limited to enameled copper wire, nitrile rubber, nylon and the mixture of nylon doped poly (3,4-ethylenedioxythiophene) and polystyrene sulfonate. Furthermore, in the above-embodiment, enameled copper wire is used. 
     By adjusting the number of layers and the thickness, the contents of the first polymer material  12 , the substrate non-nanofiber fabric  31  and the second polymer material  32  in the integrated power-generating insole are controlled. The ratio between the content of the substrate non-nanofiber fabric  31  and the total content of the first polymer material  12  of the first friction component and the second polymer material  32  is controlled to control the output electrical properties of the power-generating insole, including the output voltage, current and power. 
     As shown in  FIG. 16 , “A” represents the content of the first polymer material  12 , “B” represents the content of the second polymer material  32 , and “C” represents the content of the substrate non-nanofiber fabric  31 , and “A+B” represents the total content of the first polymer material  12  and the second polymer material  32 . The abscissa in the figure represents the ratio between the content of the substrate non-nanofiber fabric  31  and the total content of the first polymer  12  of the first friction component  1  and the second polymer material  32 , and the ordinate represents the enhancement rate of the electrical properties of the power-generating insole based on fabric integration. In the present invention, the voltage value is taken as an example. When the C value is 0, that is, when the substrate non-nanofiber fabric  31  is not added as the control group, the enhancement rate of the electrical properties is 0%. As the value of “C/(A+B)” gradually increases, the enhancement rate of the electrical properties increases first and then decreases. When the value of “C/(A+B)” is between 0.4 and 1.6, the enhancement rate of the electrical properties is higher. 
     According to the present invention, in the above—embodiment of the present invention, two layers of the substrate non-nanofiber fabric  31  and is the second polymer material  32  are combined to form the flat fabric composite component  3 .
