  • Integrated polymer-derived ceramic thin-film sensor produced by laser pyrolysis and additive manufacturing and fabrication method thereof
    Patent number: 12371384
    Abstract: An integrated polymer-derived ceramic (PDC) thin-film sensor produced by laser pyrolysis and additive manufacturing and a fabrication method thereof are provided. Using a metal component or an insulating material as a substrate, a PDC-doped composite insulating film layer with high density, high insulation, and high temperature resistance is formed by a layer-by-layer laser pyrolysis and additive manufacturing on the surface of the metal component, and a strain sensitive layer with excellent electrical conductivity is obtained by Weissenberg direct writing process PDC-doped filler sensitive grid on the composite insulating film layer and laser pyrolysis enhancing graphitization of PDC.
