NOVELTY - An aerogel comprises graphene oxide, and poly(3,4-ethylenedioxythiophene)/polystyrene sulfonate. USE - The aerogel is useful for preparing aerogel electrode, which is useful for manufacturing pressure sensor (all claimed). ADVANTAGE - The aerogel provides pressure sensor, which has ultra-high sensitivity, wide applicable pressure range, high cycle stability, fast response time, simple preparation process and low cost. The aerogel electrode has multi-level bionic microstructure of human hair, epidermis and dermis. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the aerogel, which involves taking graphene oxide and poly(3,4-ethylenedioxythiophene)/polystyrene sulfonate as raw materials to prepare a hydrogel film, and freeze drying the hydrogel film; (2) an aerogel electrode, which comprises an electrode main component, a metal deposition layer, and the aerogel connected in sequence; (3) preparation of the aerogel electrode, which involves depositing the metal deposition layer on the electrode main component, arranging the aerogel on the metal deposition layer, and connecting the electrode main component body, the metal deposition layer and the aerogel; and (4) manufacture of a pressure sensor, which involves arranging wires on electrode main component of the two aerogel electrodes to obtain aerogel electrodes with wires, and assembling the aerogel electrodes with wires.
