METHOD OF MAKING ELECTRODES FOR MEASURING BIOPOTENTIALS Russian patent published in 2005 - IPC

FIELD: medical technique, namely manufacture of electrodes for sensing biopotentials.

SUBSTANCE: method comprises steps of successively forming on substrate electric current conducting layer by applying silver containing paste; fixing electric current conducting layer on substrate; applying electric current taking-off layer and fixing it on surface of electric current conducting layer. In order to form electric current conducting layer, electrolytic silver powder, polymeric binder and solvent are used at next relation of ingredients, mass. %: electrolytic silver powder, 40 - 60; polyvinyl butyral, 2 -10; resol phenol formaldehyde resin, 4 - 20; ethanol or propanol, 30 - 50. In order to form electric current taking-off layer, silver chloride is added at relation 1 : 1 in composition of electric current conducting layer. Electric current conducting layer is fixed to substrate and electric current taking off layer is fixed to surface of electric current conducting layer in air at 20°C for 22 - 24 hours.

EFFECT: simplified procedure of making electrodes with improved reproducibility of electrochemical parameters and operational characteristics.
