Description
Technical Field
The invention relates to the technical fields of micro-processing manufacturing technology, electrophysiological signal acquisition and the like, in particular to a bidirectional dimension adjustable electroencephalogram electrode head which is matched with a columnar dry electrode for use.
Background
The scalp electroencephalogram signal acquisition usually adopts the form of an electroencephalogram cap, and the electroencephalogram cap is a device which is provided with an electroencephalogram electrode and can firmly attach the electroencephalogram electrode to the head and the adjacent position. Generally, after the electroencephalogram cap is worn, in order to form good and stable electrical contact between an electrode and a scalp, conductive pastes containing specific ions and having proper viscosity are injected below the electrode one by one through the electroencephalogram cap and holes reserved on the electrode, in order to prevent the conductive pastes from overflowing to the periphery, common electrodes are designed into a barrel shape or a bowl shape, the injected conductive pastes are filled between the scalp and the electrode, the effects of moistening the skin and eliminating electrical isolation caused by hair are achieved, and a lower electrode/tissue impedance interface is provided for electroencephalogram acquisition. Until now, the electrode structure is matched with the conductive paste to be an electroencephalogram signal acquisition strategy with the best signal quality.
Although advantageous in terms of the quality of the electrical signal acquisition, the disadvantages of such wet electrodes are mainly three-fold: firstly, the use preparation time is long, the conductive paste needs to be injected into the electrodes one by one, and one person is difficult to wear the electrodes independently; secondly, after the electrode is used by a testee, the hair and scalp parts have serious conductive adhesive residues which can be removed only by washing the hair, thereby causing great inconvenience to the testee; and thirdly, the method is not suitable for long-term monitoring of chronic electrophysiological signals, and the conductive liquid can gradually volatilize and evaporate along with the time lapse, so that the skin-electrode interface impedance is increased.
The dry electrode technology has the advantages that the dry electrode technology does not need to be matched with conductive paste for use, can be worn and used immediately, does not need to be cleaned after use and the like, and is a key technology for the brain-computer interface technology from the laboratory to the application, so that the brain-computer electrode head which can be worn quickly is paid extensive attention to and researched.
The portable electroencephalogram electrode head-wearing proposed in the prior art can be simultaneously provided with about 20 dry electrodes. The electroencephalogram electrode head which is put forward by another prior art is matched with an electrode with a claw-finger structure, and a dry electrode cap containing 16-64 channels is pushed out according to the number of the electrodes. However, the electrode caps or the head-wearing structures all adopt spring structures with certain tightness to adapt to different skull shapes, the elastic structures are originally convenient for users to wear and simultaneously improve the comfort of the users, but the elastic structures enable the whole electroencephalogram device to easily generate tightness change and slippage with the scalp during movement, and therefore disturbance is caused to enable the quality of electroencephalogram signals of the electrodes to be reduced under the movement state.
In order to solve the above problems and other problems in the prior art, there is a need to develop an electroencephalogram electrode head which is easy and convenient to wear and can acquire electroencephalogram signals for a long time at any time and any place.
