Ceramic fiber-based high-temperature-resistant capacitive pressure sensor and preparation method thereof
The invention relates to the technical field of flexible pressure sensing, in particular to a ceramic fiber-based high-temperature-resistant capacitive pressure sensor and a preparation method thereof. The ceramic fiber-based high-temperature-resistant capacitive pressure sensor comprises upper and lower packaging layers, upper and lower electrode layers, a dielectric layer and upper and lower copper wires; the packaging layer is composed of a PET film and an organic silicon film. The inner wall of the carbon cloth fabric electrode layer is sprayed with carbon particles, the surface area of the electrode can be increased, the contact between the electrode layer and the dielectric layer is improved, and due to the giant dielectric constant and high-temperature dielectric stability of CCTO ceramic of the dielectric layer, the length-diameter ratio of nanofibers, the porous structure of a fiber film and the air permeability of the fabric electrode, the surface area of the electrode can be increased. Excellent high-temperature dielectric stability and good flexibility are shown; the high-temperature-resistant pressure sensor can be applied to a high-temperature environment, has a high signal-to-noise ratio, and can effectively resist the influence of environmental noise, so that the high-temperature-resistant pressure sensor has relatively large deformation quantity in the compression process, the electrode distance of the parallel-plate capacitor is effectively reduced, the sensitivity and the responsiveness of the sensor are enhanced, and the pressure sensor has high-temperature-resistant performance.
