Abstract: A biomedical electrode assembly for detecting electrical signals from a living subject. The electrolyte reservoir of the assembly is divided into two separate sections by a dialysis membrane. The section which is in contact with the skin of the living subject contains an electrolyte which will not irritate the skin while the other section of the electrolyte reservoir contains an electrode component and an electrolyte which cooperates with the component to produce a constant, known reference voltage. The first mentioned electrolyte is preferably isotonic saline solution and the second electrolyte is at least 3 molar potassium chloride solution.
