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.
