NOVELTY - Preparing flexible pressure sensing membrane comprises mixing 1 pts. wt. conductive material, 1-3 pts. wt. long alkyl chain small molecule material and 100-1000 pts. wt. polymer elastic material, stirring and blending to form a slurry at room temperature, coating the slurry on the surface of the base material with different roughness, solidifying in the environment with the temperature of 70-100 degrees C, peeling off the cured flexible pressure sensing film the base material, and cutting into the desired shape. USE - The method is useful for preparing flexible pressure sensing membrane. ADVANTAGE - The floor: is based on flexible pressure sensing film to make a fall alarm flexible floor; can not only be used to detect whether a person has fallen, but also due to its softness and elasticity, the injury caused by a fall is greatly reduced after a person falls. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) fall alarm flexible floor, comprising an upper protective layer, an upper electrode layer, an isolation layer, a lower electrode layer, a lower protective layer and a flexible pressure sensing film. The upper protective layer, the upper electrode layer, the isolation layer, the lower electrode layer, and the lower protective layer are bonded together in sequence. The upper protective layer, the upper electrode layer, the isolation layer, the lower electrode layer and the lower protective layer are all insulating materials. The upper electrode layer and the lower electrode layer are provided with an electrode array formed by multiple electrodes with corresponding positions. The isolation layer is provided with a through hole corresponding to the position of the electrode. Two of the flexible pressure sensing films are stacked in a cavity enclosed by the upper electrode layer, the lower electrode layer and each of the through holes; and (2) manufacturing fall alarm flexible floor, comprising preparing flexible pressure sensing membrane, printing an electrode array composed of multiple electrodes on the lower electrode layer, opening an array of through holes corresponding to the positions of the electrodes on the isolation layer, gluing the isolation layer and the electrode side of the lower electrode layer together, placing two flexible pressure sensing membranes in the through holes, where the electrode array comprises multiple electrodes is printed on the upper electrode layer and corresponds to the position of the electrode array on the lower electrode layer, gluing the electrode side of the upper electrode layer and the isolation layer together, sticking an upper protective layer and a lower protective layer on the outer side of the upper electrode layer and the outer side of the lower electrode layer, respectively, and imprinting FPC on the electrode.
