Non-polarized geophysical electrode

摘要

The non-polarized geophysical electrode (10) has an electrically conductive metal disk (17) mounted at its bottom opening (15). A mixture (23) of an adhesive such as epoxy, inorganic binder, or RTV silicone, and fine particles in micron or nano size of graphene, nanotube or graphite is applied on the outer bottom surface of the conductive metal disk (17). A lead wire (19) of the electrode is connected to the inner surface of the conductive metal disk (17) and extends outward through a liquid-tight strain relief (22) mounted at a cap (16) provided at the top of the housing (11) of the electrode.
