Zusammenfassung: | The invention is suitable for the technical field of sensor manufacturing, and provides a preparation method of a braided grid flexible strain sensor, which adopts a blending or 3D printing method, a conductive material is compounded on the surface of a flexible substrate to form a conductive channel, the conductive channel is cut or printed into a linear shape, and an electrode is packaged to obtain a linear flexible strain sensor. The sensor is vertically and crossly woven into a grid, and the grid is packaged in a flexible film made of the same substrate material to form a grid device. The probes with different forces and different sectional areas are used for pressing different positions of the grid, the response of the sensor is tested, and the result shows that the grid structure can identify the pressing position, the pressing surface size and the force size. The device, a hardware circuit, an STM32 single-chip microcomputer and a display module form external hardware of an interaction system, a softwa |
