Abstract: A bioelectricity acquisition electrode, comprising a liquid storage member, an electrical wire and an electrode. The electrode is electrically connected to the electrical wire, is in contact with the liquid storage member and has a contact surface for direct contact with skin, and the bioelectricity acquisition electrode is configured such that conductive liquid accommodated in the liquid storage member can penetrate the electrode and be in contact with the skin in a state where the contact surface is in contact with the skin. When in use, the electrode easily passes through the hair to make direct contact with the scalp. When the electrode passes through the hair, the conductive liquid on the electrode is less likely to adhere to the hair. Even for the conductive liquid adhered to the skin, it is easier to clean, and does not require immediate cleaning or even cleaning at all. When the electrode accommodating the conductive liquid is in close contact with the scalp, conduction in the form of ion channels can be generated, and capacitive inductive conduction can also be generated, and therefore the acquired electroencephalogram signals are more stable and accurate. The present invention ensures a more convenient usage and a simple operation, and allows wearing to be performed by one person.
