Abstract

The invention discloses an electroencephalogram electrode head-mounted instrument, which comprises an electrode fixing plate and a head belt, wherein the electrode fixing plate is a ball-lacking shaped curved-surface surface plate and is manufactured through 3D printing according to the head appearance of a subject, and the electrode fixing plate is provided with a plurality of electrode assembling holes used for placing electrodes; and the head belt is provided with the electrode fixing plate and is configured to cover the head of the subject. The head-mounted instrument is convenient to operate, is firmly worn and is suitable for a scene of a long-term test.

Description

technical field [0001] The present invention relates to related technical fields such as micromachining and manufacturing technology and electrophysiological signal acquisition, and in particular to a head-mounted EEG electrode with two-way adjustable dimensions used in conjunction with a columnar dry electrode. Background technique [0002] Scalp EEG signal acquisition usually takes the form of an EEG cap, which is a device that is equipped with EEG electrodes and can firmly attach the EEG electrodes to the head and its immediate vicinity. Under normal circumstances, after the EEG cap is worn, in order to form a good and stable electrical contact between the electrodes and the scalp, it is necessary to inject specific ions under the electrodes one by one through the holes reserved on the EEG cap and the electrodes. In order to prevent the conductive paste from overflowing around, the general electrodes are designed in the shape of barrel or bowl, and the injected conductive...
