Wearable EEG Systems

Conventional EEG systems tie the participant to a desk with cables. g.tec's wearable EEG systems remove that limit: high-quality brain signals keep being recorded while the participant moves freely.

The g.Nautilus series offers a wireless link of up to 10 metres over 2.4 GHz digital transmission. g.SAHARA hybrid active electrodes need no gel, while g.SCARABEO active wet electrodes deliver low-noise signals even during movement. Both electrode types can be used with the same cap.

g.Nautilus Research lets researchers take their EEG studies out of the lab and into real-life conditions. Brain activity is recorded without interruption while the participant walks freely through a shopping centre, a street or a workplace.

Because g.SAHARA hybrid active electrodes can be used dry or wet, no hair washing is needed; this is critical for high-altitude medicine and field studies in remote locations. g.Nautilus Research is widely used in neuromarketing, consumer behaviour and environmental neuroscience research.

g.Nautilus Research is suited to EEG recording in vehicles, aircraft, flight simulators and high-acceleration simulators for pilots and astronauts. Its easy set-up and high tolerance of movement deliver reliable data in these demanding environments.

In-vehicle EEG makes it possible to develop real-time warning systems for monitoring driver attention, fatigue and cognitive load. g.tec's publications document both pilot mental workload measurement in flight simulators and neuroergonomics research extensively.

Weighing about as much as a climbing carabiner (~140 g) and extremely compact, g.Nautilus Research is made for sports science research. It delivers high-quality EEG even during running, jumping and high-acceleration movements.

g.SCARABEO active wet electrodes deliver data with few artefacts in sport, while g.SAHARA dry electrodes are ideal where washing hair is impossible, as in high-altitude medicine. It is used in studies of athletic performance, concentration and motor learning.

Combined with g.SENSOR fNIRS, g.Nautilus Research records both EEG and fNIRS (functional near-infrared spectroscopy) signals simultaneously from the same cap. In addition to 64/32/16/8 EEG channels, 8 fNIRS channels are ready for use within minutes.

EEG provides high temporal resolution while fNIRS measures oxygen-based brain activity. Together they reveal far more complete profiles of brain activity in cognitive neuroscience, clinical research and neurorehabilitation.

At the Ars Electronica Festival, Serbian artist Dragan Ilic controlled a KUKA robot fitted with hundreds of pens through mental commands, using the g.Nautilus wireless EEG device. The 64-channel system, which supports the motor imagery, P300 and SSVEP BCI paradigms, was demonstrated live in front of thousands of visitors.

g.Nautilus Research also works with VR experiments: EEG can be recorded while the participant wears a VR headset. It is the platform of choice for embodiment research, neurofeedback in virtual environments and BCI-VR integration.
