Abstract

The invention discloses a dry-wet general type electroencephalogram sensing electrode. The dry-wet general type electroencephalogram sensing electrode comprises a shell and a sensing contact, whereinthe sensing contact comprises a contact shell, a first electrode and a second electrode; the first electrode and the second electrode are arranged on the contact shell; the contact shell is arranged on a housing; the housing is matched with the contact shell so as to form a current guiding channel which can guide a conductive medium; and the conductive medium can be drained to the middle of the first electrode and a scalp and / or the second electrode and the scalp through the current guiding channel. The dry-wet general type electroencephalogram sensing electrode disclosed by the invention canbe used as a dry electrode, a half-dry electrode or a wet electrode according to actual situations, and thus, the dry-wet general type electroencephalogram sensing electrode can be applied to different application scenes.

Description

technical field [0001] The invention belongs to the technical field of brain-computer interface, and in particular relates to a brain-electricity sensing electrode. Background technique [0002] Electrodes play a key role in the process of scalp EEG signal acquisition. As the interface between the human body and external measurement equipment, the performance of electrodes directly determines the quality of EEG signal acquisition. At present, there are three types of contact non-invasive electrodes: dry electrodes, semi-dry electrodes (based on conductive liquid electrodes), and wet electrodes (based on conductive paste electrodes), each of which has advantages and disadvantages in different application scenarios. Dry electrodes are easy to use and do not require A lot of preparation work, but the signal-to-noise ratio is low and the stability is poor. It is generally used in occasions where the quality of the EEG signal is not high; the signal quality of the wet electrode i...
