The invention relates to a headband device with the function of collecting forehead electroencephalogram signals, belonging to the technical field of brain-computer interface; it solves the problem of poor adaptability to different head shapes and contact between electrode sheets and head skin in the prior art of electroencephalogram signal acquisition equipment Insufficient, poor contact elasticity and low use comfort. The invention provides a headband device with computer signal acquisition function, comprising an EEG signal acquisition unit, an EEG processing and communication unit, a battery unit and an elastic unit; wherein, the EEG signal acquisition unit is provided with flexible dry electrodes and Cylindrical boss, the flexible dry electrode is connected with the cylindrical convex ball hinge; the flexible dry electrode is equipped with a spring, and the electrode piece on the flexible dry electrode is connected by the ball hinge and the action of the spring, which can closely fit the wearer's forehead skin. Collect EEG signals. The headband device provided by the invention is suitable for wearers with different head shapes, is comfortable to wear, and can conveniently, accurately and reliably complete the collection of electroencephalogram signals.
Description
technical field [0001] The invention relates to the technical field of brain-computer interface, in particular to a headband device with the function of collecting forehead EEG signals. Background technique [0002] The EEG signal is a synthesis of local neuron electrical activity recorded from the intracranial or extracranial scalp of the high brain. It contains rich physiological information and can be used to evaluate the wearer's attention and relaxation. It can also be used for brain The detection and treatment of internal diseases and the field of intelligent control. [0003] The existing EEG signal acquisition device has the following two problems when collecting the wearer's EEG signal: one is poor adaptability to wearers with different head shapes; The impedance is large, and the contact flexibility between the electrode and the scalp is poor, and it is uncomfortable to wear and use. Contents of the invention [0004] In view of the above analysis, the purpose ...
