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.

  • Combination of active electrodes and active shielding

  • Resistant against electrical and movement artifacts

  • Real-time measurement of sensor impedance

  • Research-quality EEG amplifier: 24-bit ADC, low-noise, high dynamic range inputs with flexible configuration of sample rates, bandwidth and channels

Fast, Easy and Mobile

The Quick-20 is a complete portable EEG system in a wearable, lightweight package. Data can easily be streamed wirelessly via Bluetooth or recorded to a microSD card.

  • Low-noise dry electrodes that require minimum prep and no clean-up

  • Fully wireless: no cords for data recording or triggering

  • Comfortable without any restrictions on subject movement

  • Lightweight and wearable


Like all Cognionics, the Quick-20 is designed to interface with all of the hardware and software tools necessary for advanced neuroscience research.
