NOVELTY - Preparing inter-woven network of graphene based self-repairing sensor comprises e.g. adding inter-woven nickel dendrite network into mixed solution of alcohol and acetone, under 200-400 W condition ultrasonic washing for 40-80 minutes, repeatedly washing by the de-ionized water, drying with argon gas, cleaning and blowing-drying the obtained material to obtain forest-shaped nickel dendritic crystal interleaving network module, cleaning and blowing-dry forestshaped nickel dendritic crystal interlacing network as the growth template with chemical vapor deposition. USE - The self-repairing sensor is useful in medical diagnostics, artificial electronic skin bionic robot and flexible touch screen. ADVANTAGE - The sensor has high sensitivity, strain capcity, and repair after overload damage. DETAILED DESCRIPTION - Preparing inter-woven network of graphene based self-repairing sensor comprises (i) adding inter-woven nickel dendrite network into mixed solution of alcohol and acetone, under 200-400 W condition ultrasonic washing for 40-80 minutes, repeatedly washing by the de-ionized water, drying with argon gas, cleaning and blowing-drying the obtained material to obtain forest-shaped nickel dendritic crystal interleaving network module, the the cleaning and blowing-dry forestshaped nickel dendritic crystal interlacing network as the growth template with chemical vapor deposition, the growth temperature is 1000-1010 degrees C, the methane flow rate is 30-40 sccm, the hydrogen flow rate is 10-20 sccm, the growth time is 20-30 minutes, cooling to room temperature to obtain forest-shaped graphene growth on the growth template of interwoven network, and interleaving the graphene forest-shaped structure, (ii) the lower end on the network side and end faces are slowly into uncured soft gel interior and heating, solidifying into depth of the forest-shaped graphene network thickness of 20-30% to obtain upper lower end face covered by the gel of the forest-shaped graphene network, (iii) the lower end surface obtained by step (ii) subjecting to gel-coated graphene forest shaped interlacing network injecting etching liquid to remove the metal nickel framework, drying after cleaning, the flexible substrate on the forest-shaped graphene network, and (iv) on the flexible substrate forest-shaped graphene network two-side coating silver or physical vapor-phase deposition metal film as electrode, and lead-out wire from the electrode, the electrode layer coated silicon rubber or polydimethylsiloxane, and drying the silicon rubber or polydimethyl siloxane at 50 degrees C in blast drying box for 2 hours to obtain self repairing sensor.
