ABSTRACT:
Physiological electrode elements are constructed of tin and stannous chloride. The tin may be provided in any of a variety of ways, such as a solid tin plate or foil, or the tin may be plated over either an electrically conducting or electrically non-conducting substrate. A quantity of stannous chloride is affixed to the tin. A suitable conducting medium, such as a saline gel, is placed over the stannous chloride to provide a conductive path for electrical current between the tin and the skin of a patient to which the electrode is attached. In a particular preferred embodiment, the tin-stannous chloride electrode elements are made considerably larger than conventional ECG electrodes in order to be able to convey relatively large amounts of electrical energy associated with stimulating and therapeutic applications, as well as providing low impedance to the passage of the relatively small signals associated with monitoring.
