▎ 摘　　要

NOVELTY - A flexible temperature sensing material comprises three-dimensional fiber material, conductive substance and hydrophobic substance attached to fiber surface fiber. The conductive material comprises carbon nano-tube. The hydrophobic material comprises reducing graphene oxide. The three-dimensional material fiber a cotton sheet. USE - Flexible temperature sensing material for use in a flexible temperature sensor i.e. flexible health monitoring device for monitoring body temperature of a user (claimed). ADVANTAGE - The flexible temperature sensing layer and the substrate layer of the flexible temperature sensor are fiber of material, so has good ventilation property, at the same time, because the temperature sensor does not affect the precision of the measurement due to sweat. Because the three-dimensional material fiber is heated and expanded, the conductive material is dispersed, so that the conductivity is reduced, the three-dimensional material fiber cold shrinkage, and the conductor material on the aggregation is improved. The hydrophobic treatment material dispersion is prepared by dissolving a hydrophilic treatment material in first organic solvent, first drying is soaked in first dryer liquid for second drying to obtain the three-dimensional fiber material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a preparation method of flexible temperature sensing material; and (2) a preparation method of flexible temperature sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the flexible temperature sensor of a flexible temperature sensing material.
