<p>PROBLEM TO BE SOLVED: To make an electrode thin, lightweight, easy to handle, excellent in mass-productivity, and relatively inexpensive, excellent in workability in electrode installation, permitting a precise measurement. SOLUTION: Non-polarizing electrodes 44 each having a sheet type electroconductive polymeric gel body jointed with an electrode element are arranged so that the gel bodies are stuck on a ground 46, and the non-polarizing electrodes detect potentials to analyze the ground structure. For example, non- polarizing electrodes having sheet type conductive macromolecular gel bodies jointed with silver/silver-oxide layers of electrode elements are dispersedly arranged along a measurement line as current electrodes C1 and C2 and potential electrodes P1, P2..., so that the electroconductive polymeric gel bodies are stuck on the ground, and alternate DC currents are supplied from the current electrodes and the potential electrodes detect potentials and their variations to find the specific resistance and charging rate, and the ground structure is analyzed based on them.</p> |
