FLEXIBLE DRY ELECTRODE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/045107
Kind Code:
A1
Abstract:
The present invention provides a flexible dry electrode and a preparation method therefor. The preparation method for the flexible dry electrode comprises the following steps: preparing a flexible PDMS mixture; providing a substrate; coating the substrate with the flexible PDMS mixture, forming a polymer film after curing, stripping the polymer film, and placing same in a dopamine hydrochloride solution for soaking; preparing a metal nanowire solution; coating the polymer film with the metal nanowire solution to obtain a metal nanowire-polymer film; and placing the metal nanowire-polymer film in a noble metal salt solution for reaction to obtain a flexible dry electrode. In the present invention, the flexible PDMS mixture is used, the generated polymer film is a flexible film having good biocompatibility and skin attachment, so that the influence of a motion artifact during use is reduced, and the flexible film is suitable for human electrophysiological monitoring.
