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.
