The manufacturing process of the touch device comprises the following steps:
first, a transparent first electrode layer 2 is formed on a substrate base plate 1 through deposition, photolithography, development and other processes, wherein the material of the first electrode layer 2 may be graphene or nano silver wire, the graphene and nano silver wire are thin and tough, and the substrate base plate 1 may be a transparent polymer material such as polyimide.

The specific working principle of the touch device is as follows:
the material of the first power generation layer 3 and the material of the second power generation layer 4 are different from each other in the ability of binding electrons, both of them can adopt insulating dielectric medium generating electricity by friction, and because the first power generation layer 3 and the second power generation layer 4 have a triboelectric effect and electrostatic induction, the first power generation layer 3 and the second power generation layer 4 can form a friction nano-power generation electrode so as to provide power for the touch device, and the friction nano-power generation electrode is not used as a power supply, but is used as a self-driven sensing element of the touch device, when the touch device is touched, an electric signal can be generated, and the occurrence position of a touch action can be judged by the electric signal, specifically:
when people touch the substrate 1, a certain pressure is applied to the substrate 1, the first electrode plate and the first power generation layer 3 elastically deform towards the second power generation layer 4 under the action of the pressure, and because a gap is formed between the first power generation layer 3 and the second power generation layer 4, when the first power generation layer 3 contacts the second power generation layer 4 under the action of the pressure, atoms in the first power generation layer 3 and the second power generation layer 4 can contact with each other, and because the material of the first power generation layer 3 and the material of the second power generation layer 4 have different binding capacities for electrons, according to the principle of triboelectric effect, electrons in the material with weak binding capacity are transferred to the material with strong binding capacity, so that one power generation layer is positively charged, the other power generation layer is negatively charged, and electric fields are just shielded from each other, and no current passes through the detection circuit 7.
When people remove the pressure applied on the substrate 1, the first power generation layer 3 can deform in the direction away from the second power generation layer 4, so that the distance between the first power generation layer 3 and the second power generation layer 4 gradually increases, and because opposite charges exist between the first power generation layer 3 and the second power generation layer 4, the first power generation layer 3 and the second power generation layer 4 generate a potential difference, electrons of the first electrode layer 2 and the second electronic layer can be transferred through the detection circuit 7 under the action of the potential difference to realize current, and the detection circuit 7 can judge the touch position by detecting the current existence information.
When the first electrode layer 3 is leveled, the electric potential between the first electrode layer 2 and the second electrode layer 6 is equal, so that no current is generated between the first electrode layer 2 and the second electrode layer 6.
When the underlying substrate 1 is touched and pressed again, the first power generation layer 3 and the second power generation layer 4 approach each other again, so that the potential difference between the first electrode layer 2 and the second electrode layer 6 is reduced, electrons between the first electrode layer 2 and the second electrode layer 6 flow in the opposite direction through the detection circuit 7, and after the first power generation layer 3 and the second power generation layer 4 are contacted, the potential difference between the first electrode layer 2 and the second electrode layer 6 disappears, so that the current in the detection current disappears.
