▎ 摘　　要

NOVELTY - Preparing graphene aerogel slurry material comprises dropping solution into the graphene oxide solution; performing reduction reaction at 60-80 degrees C until the solution is changed from brown yellow to grey black, washing to obtain the reduction-oxidation graphene suspension, adding carbomer to the reduced graphene oxide suspension liquid, mixing uniformly, where the reducing graphene oxide suspension of m (water): m (carbomer) is 90-120:1, 10-20 mg/ml sodium hydroxide to obtain the graphene aerogel slurry. USE - The bionic electronic skin is used for intelligent robot, bionic artificial limband portable medical device. ADVANTAGE - The bionic electronic skin prepared by graphene sensor has high sensitivity and wide detection range. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a graphene aerogel slurry prepared by the preparation method of graphene aerogel slurry, a graphene sensor prepared by graphene gas gel slurry by direct ink writing method; and (2) a biomimetic electronic skin prepared different density of the graphene sensor
