Abstract

The invention relates to a method for measuring the space curvature of a deformable curved surface and a method for manufacturing an inductance type space curvature measuring sensitive element, and solves the technical problems that an existing flexible mechanical arm curvature measuring method is complex, engineering operation is inconvenient, and cost is high. The measuring method comprises the following steps: firstly, manufacturing a screen printing plate, the screen printing plate being provided with meshes of a coil part; secondly, tightly attaching a screen printing plate to the surface of the object capable of being bent and deformed, coating the screen printing plate with a layer of conductive powder, extruding the conductive powder through a scraper, transferring the conductive powder to the surface of the object capable of being bent and deformed through meshes of a coil part on the screen printing plate, and forming a conductive coil on the surface of the object capable of being bent and deformed; then, one end of the conductive coil being connected with an interface lead, and the other end of the conductive coil being connected with an interface lead; and finally, measuring the inductance value of the conductive coil, and calculating the curvature of the bendable and deformable object according to the inductance value of the conductive coil. The method is widely used for measuring object deformation parameters.
