Abstract:
1. A head-mountable device including an electrode array for measuring bioelectrical signals generated by a cerebral cortex of a brain configured such that individual electrodes are radially adjustable for individual variations in head size and shape comprising: a plurality of head-mountable device sections; a plurality of mechanical fasteners connecting the head-mountable device sections; wherein the head-mountable device sections can be bent upward and downward by the mechanical fasteners during application and removal of the device such that the device sections are moveable relative to one another; an array of resilient sleeves within each head-mountable device section, each sleeve housing an individual electrode, the resilient sleeve being deformable for self-orienting 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 the electrode; and a damper portion integral of at least one of the resilient sleeves and configured to be deformable for maintaining the orientation of the individual electrode relative to the scalp portion beneath the individual electrode.
