NOVELTY - Preparing amino-modified graphene oxide-mesoporous silica ball-aqueous polyurethane fabric-based humidity sensor involves preparing humidity sensor substrate, preparing amino-modified graphene oxide, preparing mesoporous silica, and preparing humidity sensor. USE - Method for preparing amino-modified graphene oxide-mesoporous silica ball-aqueous polyurethane fabric-based humidity sensor used in human respiration monitoring, and is convenient for real-time feedback of human body information (claimed). ADVANTAGE - The amino-modified oxidized graphene-mesoporous silicon dioxide ball-aqueous polyurethane fabric humidity sensor increases the contact area of the water molecule through the mesoporous structure of silicon oxide (m-SiO2), and the water molecules can quickly reach GO surface through the m-SO2, to effectively improve the response rate and sensitivity of the humidity sensor. The humidity sensor has better hydrophilic performance and larger specific surface area.
