An electrode device for sustainable detection

An electrode device for sustainable detection includes: a fixing frame provided with a fixing groove on one side; a sponge body correspondingly embedded in the fixing groove in a detachable manner, provided with a wire embedding groove, and can provide electrical signals for direct touch with surface skin or mucous membrane to be read; a liquid delivery tube, one end of which is connected to a liquid storage barrel that can store an electrolytic fluid, and the other end of which is connected to wire embedding groove, with one end of the liquid storage barrel being provided with a coupling element; and an electrode element, which can penetrate inside the liquid delivery tube, with one end of the electrode element being arranged in the wire embedding groove, and the other end of the electrode element being placed inside the liquid storage barrel. When the electrode element infiltrated with the electrolytic fluid is in contact with the skin or mucous membrane on any surface of the human body, the coupling elemen
