An adhesive electrode for the registration of electric and electrobiological signals and/or for stimulating a patient includes a patient contact portion and a transmission portion. The patient contact portion includes a layer of adhesive electrolyte material in contact with the patient's skin, a layer of conductive material, and a layer of insulating material. The transmission portion is also connected to the conductive layer. The layer of conductive material includes at least partially a layer of magnetic material, the transmission portion being removably secured to the layer of magnetic material.
