Abstract

An electrode for living bodies consisting of a fine metal wire at least part of the surface of which is directly coated with a porous membrane having fine pores of an average pore diameter of greater than 0.01 .mu.m. The electrode makes it possible to measure the oxygen concentration in the blood vessels and in the living tissues with increased stability and improved response characteristics. Particularly good results are obtained when the porous membrane is a non-homogeneous structure using a cellulose acetate.
