The invention discloses a flexible dry electrode with small contact impedance and a npreparation method thereof, which relates to the technical field of medical devices, and is ncomposed of a flexible electrode body and an electrical connector. The flexible electrode nbody is made of flexible material silicone rubber and conductive nano material. The flexible nconductive material silicone rubber is used as the base material, and the conductive nano nmaterial is added to mix and disperse evenly, then the flexible electrode body is heated under npressure and solidified. After two-stage vulcanization, it is further cross-linked, so that the nprepared dry electrode has excellent conductivity and flexibility and has good geometric nadaptability. It can be applied to the irregular skin surface for close contact, increase the ncontact area between the dry electrode and the skin, reduce the contact impedance between nthe skin and the electrode, and effectively realize the daily activity monitoring of the brain nelectrical signal. It has a wide range of application scenarios in mental health consultation nand brain-computer interface in the military, schools and hospitals.n-3/11n2 n11 nFIG. 3 |
