Abstract
In a brain wave detecting system, in one embodiment, a flexible hat is placed on the head of the patient. The hat contains a plurality of electrodes conforming to the hat. A circuit board having a low-noise integrated circuit amplifier may be mounted thereon. Each electrode uses a plurality of metal conductive fingers which protrude through the hair to the scalp and provide multi-contact sites on the scalp for each electrode. The tips of each electrode contact the user's scalp to provide a redundancy of contacts for each electrode.
Claims12
An electrode system to detect brain waves from the scalp of a patient, the system comprising:
- a head gear adapted to fit on the head of the patient;
- at least one electrode mounted on the head gear to contact the scalp, said at least one electrode comprising a plurality of stiff conductive fingers each having a free end portion, a tip means at the end of each finger free end portion to contact the scalp of the patient without abrading or hurting the scalp, said tip means including a conductive tip to contact the scalp, said tip having a diameter of greater than 0.1-inch at its contact with the scalp and a surface which is smooth, non-pointed and non-abrasive to the scalp, and conductive means including said fingers to conduct brain wave signals from the tips.
