Abstract
A force-controlled electroencephalogram (EEG) monitoring device maintains a constant pressure between electrodes and the scalp of a user thereby increasing user comfort. Arms on the EEG monitoring device position the electrodes in contact with specific regions on the head of the user. The dimension, shape, and curvature of the arms affect the amount of force with which an electrode is held in contact with the user's scalp. The amount of pressure may be different for different regions of the user's head to achieve a balance between comfort and conductivity. The amount of pressure may be further modulated by the use of spring-loaded electrode holders that allow an electrode to move relative to the holder. To further improve user comfort, the tips of the electrodes may be hemispherical rather than pointed. The EEG monitoring device can be used as input for a brain-computer interface (BCI).
