ELECTRODE ARRAY AND METHOD OF PLACEMENT

摘要

A headset for detecting brain electrical activity may include a flexible substrate having first and second ends each configured to engage an ear of a subject and dimensioned to fit across the forehead of a subject. The headset may also include a plurality of electrodes disposed on the substrate and configured to contact the subject when the headset is positioned on the subject. First and second electrodes may contact top center and lower center regions of the forehead, respectively, third and fourth electrodes may contact front right and front left regions of the forehead, respectively, fifth and sixth electrodes may contact right side and left side regions of the forehead, respectively, and electrodes included within the securing devices may contact the ear regions. The third and fourth electrodes may be moveable in at least a vertical direction relative to the other electrodes.

主权项

1. A headset for detecting brain electrical activity of a human subject comprising:
a flexible substrate dimensioned to fit a forehead of the subject having a first end and a second end, wherein the first end and the second end each includes a securing device configured to engage an ear of the subject to position the substrate across the forehead, and wherein the substrate includes at least one expansible region permitting a distance between the first end and the second end to selectably vary; a plurality of electrodes disposed on the substrate so that the electrodes contact the subject when the headset is positioned on the subject;
wherein a first electrode is configured to contact a top center region of the forehead, a second electrode is configured to contact a lower center region of the forehead, a third electrode is configured to contact a front right region of the forehead, a fourth electrode is configured to contact a front left region of the forehead, a fifth electrode is configured to contact a right side region of the forehead, and a sixth electrode is configured to contact a left side region of the forehead;wherein one electrode is included within each securing device and configured to contact an ear region of the subject when the headset is positioned on the subject, andwherein at least the third electrode and the fourth electrode are movable in at least a vertical direction relative to the other electrodes when the headset is positioned on the subject; and flexible circuitry in the substrate operably coupled to each electrode.
