Abstract

This invention relates to the field of electroencephalogram (EEG) signal acquisition equipment, specifically to a head-mounted device for EEG signal acquisition. The device includes a head-mounted main body, electrode components, and a control module. The head-mounted main body is equipped with an adaptive adjustment mechanism, a fit monitoring mechanism, and a detachable sealed electrode structure. The adaptive adjustment mechanism adjusts the head circumference of the head-mounted main body and the fit position and pressure of the electrode components. The fit monitoring mechanism is electrically connected to the electrode components and the control module, and monitors the fit between the electrode components and the scalp in real time. The detachable sealed electrode structure is detachably connected to the head-mounted main body, ensuring the conductivity stability of the electrode components and facilitating disassembly and cleaning. The control module automatically adjusts the fit position and pressure of the electrode components based on the fit monitoring results. This invention achieves coordinated adjustment of head circumference size and electrode fit position and pressure, and monitors and automatically corrects the electrode fit in real time.
