Abstract

Electrical detector to be fixed on the skin surface for biometrical observations, consisting of a silver silverchloride electrode and outlet placed in a casing, further of a biologically harmless ion conducting gel placed between the skin surface and the electrode, the electrode having a porous structure containing silver grains of less than 800 mu m linear size and its density falling between 2 and 8 g/cm3, the surfaces of the individual silver grains being bound by cohesion to the surfaces of the adjacent silver grains, respectively to the surface of the outlet shaped from silver and the surfaces of the silver grains not participating at the cohesive binding being coated by a known silver-chloride layer.
