Specifically, the elastic cup body can be made of materials such as rubber and the like which are easy to deform under stress. Specifically, the cup holder and the elastic cup body can be integrally arranged or detachably connected. When in use, the cup base is made of hard materials such as plastics, PLA biodegradable plastics, polylactic acid, ABS plastics and the like, namely, the cup base is a hard shell cup base. In practical application, the elastic cup body can be integrally fixed on the hard cup base, so that the integral arrangement of the elastic cup body and the hard cup base is realized; the clamping groove can be arranged on the hard cup base, so that the end part of the elastic cup body slides into the clamping groove, and the detachable connection of the elastic cup body and the clamping groove is realized. The conductive structure 20 is mounted on the cup holder, and specifically, the conductive structure may be a structure having a conductive function, such as a metal ring. During application, the spring-type electrode provided by the embodiment of the application is connected with external equipment (such as electroencephalogram EEG acquisition equipment) through the lead 21, so that signals acquired by the spring-type electrode provided by the embodiment of the application are sent to the external equipment. The spring assembly is arranged in the cup body and comprises a spring 31, a sponge 32 and an electrode plate 33, the sponge is arranged inside the spring 31, one end of the spring 31 is connected with the conductive structure 20, the other end of the spring is connected with the electrode plate 33, and a plurality of leakage holes 330 are formed in the electrode plate 33. Specifically, the electrode sheet may be provided as a circular or oval metal sheet. Specifically, the spring may be fixed to the electrode tab by welding.
