[Class 81 (ii)] Condenser electrodes for short-wave and ultra shortwave therapy are characterised by the provision of a dielectric layer c of mouldable non-elastic substance retaining the shape imparted to it; preferably a substance mouldable on warming such as paraffin wax is employed. The dielectric layer is mounted upon a metal plate connected to a conducting rod b or upon a layer d of material having a higher dielectric constant such as hard rubber or artificial resin, the layer d being covered by a metallic layer e, made of foil or produced by spraying. In use the electrodes are stored in a heated enclosure, or on heated plates of corresponding shape, and are moulded to the part to be treated before application thereto ; the moulding may include the production of a cavity c<1> when boils or the like are to be treated. In a further modification the mouldable layer is mounted on a glass container enclosing a metal plate, movable towards and away from the body, to adjust the capacity of the electrode, by a stem passing through the container cover.
