NOVELTY - A conductive carbon slurry comprises 1-25 wt.% grapheme, 0.04-1.5 wt.% carbon nano tube; 0.001-1 wt.% dispersant, 5-45 wt.% oil resin; 1-10 wt.% thickening agent, 0.01-5 wt.% coupling agent, 25-70 wt.% first solvent and 20-40 wt.% second solvent. USE - Conductive carbon slurry for use in a flexible pressure sensor. ADVANTAGE - The conductive carbon slurry has high sensitivity, high stability, low lowest detection limit, resistance to bending, strong adhesion between the flexible substrate, increased electrical resistance, high-pressure sensitivity, and can sense a micro-pressure change. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing conductive carbon slurry for flexible pressure sensor comprising (i) mixing graphene, carbon nanotube, dispersant, and the first solvent, grinding until the size of the slurry is 0.01-5 mu m, (ii) adding oil resin, coupling agent and the second solvent into the slurry obtained in the step (i), grinding (iii) adding the thickening agent into the slurry obtained in the step (ii), stirring, grinding until the granularity is less than 6 m, and (iv) defoaming the slurry obtained in the step (iii) to obtain the conductive carbon slurry; and (2) a flexible pressure sensor, comprising a flexible substrate and a pressure sensing layer formed on the flexible substrate, the pressure sensing layer is formed by curing the conductive carbon slurry coating on the flexible substrate.
