[Optimizing electrode contact with adhesive agents].
An evaluation of three hydrogel-forming substances carboxylmethylamylopectine sodium, carboxymethylcellulose sodium, hydroxyethylcellulose used in the G.D.R. is presented in respect of their quality to form a electrodes-fixing gel. Useful compositions were tested on their fixation-power, physiological compatibility, decreasing of skin-resistance, oppression of interferences and preparation consistence during six month. A gel consisting on 15% hydroxyethylcellulose, 20% glycerol, 0.9% sodium chloride and 64.1% preserved water has been accepted as useful for storage and for an interferenceless conduction of biopotentials for several hours.
