Abstract: A head-mountable EEG electrode-containing device is provided based on radially adjustable electrodes to fit the wearer's unique head size and shape. The head-mountable device with an electrode array positioned therein includes multiple head-mountable device sections that are interconnected by mechanical fasteners to facilitate sizing and positioning of the head-mountable device. An array of resilient sleeves is positioned within each head-mountable device section. Each resilient sleeve houses an individual electrode and is deformable for self-orienting. The deformation of the sleeve is such that a central axis passing through the individual electrode housed within the resilient sleeve is maintained in a position approximately normal to a plane tangential to a scalp portion positioned beneath that electrode.
