The Freedom 20R is the latest in mobile EEG technology, offering
an unmatched level of usability and signal quality for research and
practitioner applications. With the Freedom 20R, you can obtain EEG
signals on most subjects in just under two minutes. The headset, The
headset, which supports the full 10-20 System, adapts to adult and
most older child head sizes and is easy to apply with a minimum of
Measuring EEG signals in real-world environments is tough. Unlike a
controlled laboratory environment, electrical noise from power lines,
computers and other devices easily overwhelms a conventional,
unshielded EEG system. Subject movements can induce large amplitude
electrical and physical noise overwhelming the tiny EEG signal.
To make real-world EEG acquisition possible, the Freedom 20R uses a
highly optimized combination of sensors, mechanics, and electronics
to eliminate unwanted artifacts.
