▎ 摘　　要

NOVELTY - Manufacturing of high-conductivity breathable hydrogel dry electrode involves preparing a fiber film (1) by electrostatic spinning, preparing a hydrogel film (2) containing conductive filler on the fiber film to obtain a mixed film puncturing the mixed film to ensure that air holes (4) are distributed on the mixed film, manufacturing a wavy conductor (3) by using a mixed solution mixed with prepolymer, cross-linking agent and conductor material, transferring the wavy conductor to the surface of the hydrogel film, and baking the mixed film. USE - Manufacturing of high-conductivity breathable hydrogel dry electrode (claimed) used in soft bioelectronic devices for wear-resistant devices, soft robots, and implants which can be well attached to curved surface such as cloth, organ or skin. ADVANTAGE - The method prevents conductor from being solidified on the hydrogel, provides electrode having excellent air permeability, easy to strain and attach to the skin when stressed. The wavy conductor with the elasticity of the polymer can bear large-amplitude deformation, and the surface of the wavy conductor exposed on the dry electrode is directly contacted with the skin, so that the dry electrode has lower contact impedance.
