Headset for EEG measurements
First Claim
1. A headset for measuring brain waves, comprising:
- a headset base extending in a first direction and including at least a first dry conductive foam configured to contact a subject at an ear lobe area of the subject when the subject is wearing said headset;
a crossbar member attached to said base and extending in a second direction different than the first direction and including at least a second dry conductive foam pad configured to contact the subject when the subject is wearing the headset;
at least first and second conductors respectively in contact with said first and second dry conductive foam pads; and
a third conductive foam pad disposed at a position where said headset base and said crossbar member cross each other, and a third conductor in contact with said third conductive foam pad.

Abstract
A headset and system for taking EEG measurements on the head of a test subject. The headset has a plurality of electrode sensors in predetermined anatomical positions on the head of a subject to take EEG measurements, for example of the subject'"'"'s response to certain stimuli. The electrode sensors are formed of dry conductive foam rubber pads attached to conductor elements. An individual shielded cable is attached to each sensor to carry the detected signal to a signal processor. The sensors may be formed of a carbon impregnated foam rubber pad that offers high conductivity. The sensors do not require wetting agent, and thus can be used in a very time efficient manner, and can be easily replaced for sanitary considerations.
