Quick-20 Dry EEG Headset
The Quick-20 is the latest in mobile EEG technology, offering an unmatched level of usability and signal quality to enable new research applications. With the Quick-20 system, EEG signals can be obtained on most subjects in just under one or two minutes. The headset, which supports the full 10-20 array, adapts to most older child and adult head sizes is easy to apply with a minimum of adjustments.
High Signal Quality
Measuring EEG signals in real-world environments is tough. Unlike a controlled laboratory environment, electrical noise from power lines, computers and other devices can easily overwhelm a conventional, unshielded EEG system. In addition, subject movements can also easily induce large amplitude electrical and physical noise to overwhelm the tiny EEG signal. To make real-world EEG acquisition, possible, the Quick-20 uses a highly optimized combination of sensors, mechanics and electronics to eliminate unwanted artifacts.
