▎ 摘　　要

NOVELTY - The mattress comprises a sensing layer provided with multiple flexible sensors, which are arranged in an array. The flexible sensor is provided with a conductive fabric, which is provided with a flexible substrate. A graphene film layer is formed on a surface of the flexible substrate. A signal collecting device is connected with a side of the sensing layer. The signal collecting device is electrically connected with a smart display terminal. The smart display terminal obtains user physiological parameter information according to a pressure signal or humidity signal analysis. The graphene conductive paste on the graphene film layer is a solution with a graphene/polyurethane efficient content ratio of 1-6%. A reducing agent is hydrazine, methyl hydrazine, phenylhydrazine, sodium hydroxide, potassium hydroxide, ammonia water and hydroiodic acid. The dispersant is polyvinylpyrrolidone K90. The signal collecting device comprises a signal collecting control module. USE - Used as mattress based on flexible sensor. ADVANTAGE - The mattress :has high reliability, better real-time responsiveness, high monitoring precision, high comfort level and wide range of applications. DESCRIPTION OF DRAWING(S) - The drawing shows a working principle of the mattress based on flexible sensor.
