Title:
ELASTIC DRY ELECTRODE, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/104049
Kind Code:
A1
Abstract:
Provided in the present invention are an elastic dry electrode, and a preparation method therefor and the use thereof. The preparation method for the elastic dry electrode comprises: adding a polymer material to a solvent to prepare a first solution; adding a poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid solution and a metal nano material to the first solution, stirring same, and then adding a conductive auxiliary to obtain a second solution; and soaking an elastic porous substrate in the second solution, and then carrying out a vacuumizing treatment to obtain an elastic dry electrode. According to the preparation method of the present invention, the elastic porous substrate has a porous framework structure, and poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid and a metal nano material are used as conductive components; the elastic dry electrode can be prepared by utilizing the physical adsorption of the elastic porous substrate to the poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid and the action of the polymer material, and by carrying out a vacuumizing treatment; and the prepared elastic dry electrode can be used without skin preparation, without the use of a conductive gel, has a good biocompatibility, and can further effectively avoid the influence of hair on same and improve the degree of comfort.
