  • Patent number: 11813088
    Abstract: A grip includes a core that forms a structure of the grip and has electrical conductivity, a sensing electrode for detecting a biological signal of a user, and a ground electrode that is connected with a reference voltage portion. The core, the sensing electrode and the ground electrode are insulated from one another. The core is disposed inside the grip, and the sensing electrode is exposed on a surface of the grip. The sensing electrode and the core are connected with one another via a voltage follower circuit. The ground electrode is located at such a position that the core is able to reduce a parasitic capacitance which would be formed between the ground electrode and the sensing electrode.
    Type: Grant
