Embodiment 1
[0057] This embodiment prepares the pressure sensor according to the following method:
[0058] (1) Mix and stir cellulose acetate and 1-ethyl-3-methylimidazolium hexafluorophosphate with a mass ratio of 1:1, and dry at 80°C to form a film to obtain a highly transparent dielectric layer.
[0059] (2) Coating a layer of metallic silver nanowires on one side of the transparent polyimide film by scraping the film to obtain a transparent electrode layer.
[0060] (3) The transparent dielectric layer obtained in step 1 is sandwiched between two transparent electrode layers obtained in step 2, and the surroundings are fixed with epoxy resin to obtain a flexible transparent high-sensitivity pressure sensor.
[0061] The pressure sensor prepared in this embodiment is composed of a dielectric layer and a first electrode layer and a second electrode layer respectively located on both sides of the dielectric layer. The dielectric layer includes an ion active material and a membrane mater...
Embodiment 2
[0069] This embodiment prepares the pressure sensor according to the following method:
