Ionic concentration of a mixture. The potentiometric sensor according to the invention comprises a matrix body 7: . made of the same type of material 7, which does not conduct electricity, and is chemically highly inert; . comprising a zone z sensitive to a chemical species and formed in the matrix material: - by a layer of ionic conducting material 9, intended to be placed in contact with the solution, - by a sub-layer of electronic conducting material 10, - and by an intermediate layer or thickness 11 of intimate binder, . provided with a conductor 12, made of an electrically conducting material, inserted in the sub-layer. Application to biological fluids. <IMAGE>
