Abstract: A dry electrode for medical use for recording existent biopotentials on the skin surface and for electrical stimulation of different zones of the human body. The dry electrode comprises a flexible electroconductive plate provided on its bottom side with a plurality of sharp bosses for partial skin penetration. The plate has a corrugated radial extension tongue and two orifices, a first orifice in the center of the plate and a second orifice in the tongue portion. The orifices and the tongue portion allow for different connectors to be utilized, such as a stem with a circular base, a Stillson wrench or a hook type connection. The electrode makes contact on its bottom face with a needle which penetrates and stays anchored within the skin.
