Warp and weft sensing membrane

The utility model relates to a warp and weft sensing membrane comprising high-temperature resistant insulating paper, electrically conductive ink leads and round holes. The electrically conductive ink leads are printed on the right side and the back side of the rectangular high-temperature resistant insulating paper; the electrically conductive ink leads on the same side of the high-temperature resistant insulating paper are arranged in the same direction; the electrically conductive ink leads on the right side of the high-temperature resistant insulating paper are perpendicular to those on the back side of the same; and the right side and the back side of the high-temperature resistant insulating paper, which are not printed by the electrically conductive ink leads are punched by the round holes. The warp and weft sensing membrane can accurately reflect the shapes of cracks in real time and has the advantages of low cost, high precision, good stability, and the like.
