▎ 摘　　要

NOVELTY - The method involves providing a pressure sensitive layer. An electrode layer is formed on the surface of the pressure-sensitive layer. A porous structure composite material is prepared by mixes conductive nano-material, graphene oxide, one-dimensional cellulose and dispersant to obtain a dispersion solution. Low-temperature thermal reduction treatment is carried out to the composite material sponge nano-composite material hydrogel. Supercritical carbon dioxide drying is performed to the hydrogels of the nano composite material hydgels to obtain porous structure complex material. USE - Method of preparing of flexible pressure sensor for converting mechanical information into electrical signal. ADVANTAGE - Method improves the structure flexibility of the conductive gas gel, and provided high excellent pressure-sensitive sensitivity, good rebound resilience and cycle stability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a method of preparing of flexible pressure sensor for converting mechanical information into electrical signal.
