Abstract:
1. A physiological sensor device, comprising: a flexible structure capable of being applied to a subject; a first electrode disposed on the structure for receiving a first electrical signal associated with the subject, wherein the first electrode is disposed on the structure at a location such that when the structure is applied to the subject, the first electrode is positioned over the horizontal center of the forehead of the subject; a second electrode disposed on the structure for receiving a second electrical signal associated with the subject, wherein the second electrode is disposed on the structure at a location such that when the structure is applied to the subject, the second electrode is positioned on a side of the forehead of the subject; a third electrode disposed on the structure for receiving a third electrical signal associated with the subject, wherein the third electrode is disposed on the structure at a location such that when the structure is applied to the subject, the third electrode is positioned on the side of the forehead of the subject at a position further away from the horizontal center of the forehead than the position of the second electrode; a fourth electrode disposed on the structure for receiving a fourth electrical signal associated with the subject, wherein the fourth electrode is disposed on the structure at a location such that when the structure is applied to the subject, the fourth electrode is positioned over a temple of the subject on the same side of the subject's head with respect to the horizontal center as the second electrode and the third electrode; and an optical detector disposed on the structure at a location between the second electrode and the third electrode for receiving an optical signal transmitted into the subject.
