Abstract:
An electrode assembly for application to a patient's skin, the assembly comprising an electrically insulating substrate bearing at least two spaced apart electrodes and an electrically conductive layer on the same side of the substrate as the electrodes, the layer covering the electrodes and extending continuously over the substrate between the electrodes and being applied to the patient's skin in use of the assembly, and the electrical impedance through the thickness of the layer in the region overlying each electrode being less than the electrical impedance between the electrodes laterally through the layer, wherein the assembly includes at least two spaced apart conductive members each having a base on the side of the substrate which bears the electrically conductive layer and an upstanding stud which passes through a hole in the substrate, and wherein each electrode is constituted solely by the base of a respective conductive member and the stud enables contact to be made to the respective electrode from the opposite side of the substrate.
