1. A wearable apparatus for wearing on a head of a user, the apparatus comprising: a band assembly comprising:
a flexible band member comprising band ends joined by a curved band portion of a curve generally shaped to correspond to the user's forehead;
at least one bio-signal sensor disposed inwardly along the curved band portion to provide a flexible conductive surface;
a biasing component to urge the at least one bio-signal sensor towards the user's forehead when worn by the user;
a conformable earpiece connected to one of the band ends of the flexible band member to secure the wearable apparatus to the user, wherein at least a portion of the conformable earpiece is made of conductive material to provide at least one additional bio-signal sensor in contact with an ear or mastoid bone region of the user to form around the back of the ear of the user, wherein the conformable earpiece has a depressible area to depress the conductive material against the back of the ear at a front edge and hook a bottom edge of the conformable earpiece around the ear to generate a force to secure the conductive material against the back of the ear and to urge the at least one bio-signal sensor towards the user's forehead, wherein the conformable earpiece comprises a collapsible inner hollow area configured to collapse to form around the back of the ear when worn;
at least one computer system connected to the at least one bio-signal sensor and the at least one additional bio-signal sensor to receive bio-signal data to determine a brain state of the user, the at least one computer system having at least one computer, at least one non-transitory computer readable medium including processing instructions for the computer processor to process the bio-signal data, and at least one communication subsystem for communicating the processed bio-signal data to an external computing device.
