Back in 2008 for $ 170 you can buy a device OCZ NIA, among the first to offer mass-market computer control function using facial expressions and impulses in the brain.
A group of American scientists have developed a system of dry sensors for the removal of the electroencephalogram, which does not require the use of special conductive gel and careful placement of each sensor on the human scalp. Elastic "helmet" consists of a central segment, which case built-shielded signal amplifiers and other electronics, as well as the flexible side arches that can comfortably accommodate a system of sensors on the head of any person. Total system involves processing the information received on 64 channels.
The secret of dry sensors is a special combination of coating carbon and silver printed on a flexible basis. These sensors allow electric impulses surely read brain even in the presence of obstacles in the form of hair. A special algorithm divides the EEG into several components, which, after checking with the "reference" signal cleared of extraneous noise. This implies that the device requires a calibration during operation with each of the users - desired signal disappears in the maximum resting. As an "interference" in favor of man, any physical activity, talk or even blink.
The developers believe that the invention can be used not only in medicine, but also in the creation of "telepathic interface" to work with computers and mobile electronics. Physicians using these diagnostic methods are going to treat the brain with its own resources. Related Products :
