Abstract
A headband assembly for sensing signals of brain wave frequencies of human subjects that includes an adjustable headband adapted to fit various sized heads, constructed to be quickly attached and detached by the wearer, and including electrodes that are shiftable along the headband and of a construction to penetrate the hair of the subject in making skin contact.
Claims3
A headband for sensing human physiological characteristics and the like, comprising:
- an elongated strip of adherent material having a hook surface and a loop surface on opposite sides thereof, said strip being of a length sufficient to encircle the head of the wearer,
- at least one electrode of adherent material having a hook surface and a loop surface on opposite sides thereof,
- at least one spacer of adherent material having a hook surface and a loop surface on opposite sides thereof,
- one of said hook surface and said loop surface of the electrode being plated with an electrically conductive material,
- the other of said hook surface and said loop surface of the electrode being pressed against the mating one of the hook surface and the loop surface of said spacer, the other of said hook surface and said loop surface of the spacer being pressed against the mating one of the hook surface and the loop surface of said strip and being shiftable along the length of said strip, and
- means for electrically interconnecting said plated surface of said electrode with a measuring and a correlating system.
