Wearable EEG for clinical applications
g.Nautilus Pro Flexible is a CE-marked and FDA-cleared wireless EEG headset designed for reliable recording of brain activity in medical and clinical settings. Its modular design pairs one reusable amplifier with dry or gel g.SAHARA Hybrid, wet g.SCARABEO and Safety Connector strands for additional biosignals. The strands swap within seconds on the same amplifier and are cleaned and disinfected apart from it, which makes hygiene easier and lets the same device adapt quickly to different patients, cap sizes and protocols: one device, many patients, quick set-up.
Complete electrode strands swap within seconds on the same amplifier. Clinicians choose g.SAHARA Hybrid dry electrodes, g.SCARABEO wet electrodes or Safety Connector strands for additional biosignals, as the application needs. Unlike conventional systems, the removable electrode strands are cleaned and disinfected independently of the amplifier.
Clinical EEG needs more than signal acquisition: fast patient preparation, reliable recordings, flexible electrode configurations and efficient cleaning between examinations. The system supports 8, 16, 19 or 32 channels; different electrode types are configured for different applications without changing the acquisition hardware. Removable strands simplify hygiene management and shorten turnaround between patients, which matters most in clinical settings with many recordings a day. It is a CE-marked and FDA-cleared medical device meeting IEC 60601-1 3rd edition, IEC 60601-1-2 electromagnetic compatibility, IEC 60601-2-26 for EEG devices, IEC 62304 medical software, ISO 14971 risk management, ISO 10993-1 biocompatibility and IEC 62366 usability.
Every electrode strand carries 8, 16, 19 or 32 EEG electrodes. g.SAHARA Hybrid is a hybrid active strand used dry or with gel; it needs no hair washing and suits remote and demanding clinical conditions. g.SCARABEO is a gel-based active strand with an internal impedance check; good scalp contact gives low artefacts and high signal quality. The Safety Connector strand connects g.SCARABEO and g.SAHARA Hybrid electrodes and g.Sensors body sensors. There are five configurations: a g.SCARABEO strand; a g.SAHARA Hybrid strand; g.SCARABEO with 4 Safety Connectors; g.SAHARA Hybrid with 4 Safety Connectors; the Safety Connector module only. We can work out together which strand and configuration best fit your clinical needs.
Wearable EEG headsets are becoming increasingly important in medical and clinical settings as more and more studies are conducted in the field. With g.SAHARA Hybrid or g.SCARABEO and g.LADYbird wet electrode technology, g.Nautilus Pro Flexible records at high quality without data loss. The signal travels digitally in the 2.4 GHz band, up to 10 metres indoors; a built-in 3-axis accelerometer records movement. The built-in lithium-ion battery runs for more than 10 hours with 32 channels and recharges in 2–3 hours on Qi-standard contactless inductive charging.
g.Recorder records EEG, g.HIsys processes it in real time and g.BSanalyze analyses it offline, with dedicated algorithms that remove TMS and tDCS artefacts. The g.Pype SDK for Python, the g.tec Suite 2024 APIs and g.NEEDaccess, with MATLAB, Simulink, Python and Lab Streaming Layer (LSL) support, let you build custom applications. OSCAR LIVE, which corrects movement artefacts in real time, is included in g.HIsys Professional; OSCAR PRO, which corrects them offline, in g.BSanalyze Professional.
Simultaneous recording from several g.Nautilus Pro Flexible devices is essential for developing advanced BCI systems. In applications such as neuroprostheses, communication aids for people with paralysis and brain-controlled devices, it lets complex neural signals be decoded more accurately. Data from several amplifiers decode the user's intention more precisely and reliably, improving the performance, accuracy and usability of BCI technology.
The Safety Connector strand records EMG, ECG, EOG, GSR, respiration, temperature, pulse, blood pressure and other biosignals alongside the EEG. The modular design lets each study be configured without changing the amplifier.
The light wireless design reduces cable-related artefacts and lets patients move naturally during therapies such as upper-limb rehabilitation, gait training, motor imagery and brain-computer interface training. Pre-mounted g.GAMMAcaps give fast preparation and consistent electrode placement; removable strands make cleaning between therapy sessions easier. Stroke rehabilitation, motor recovery research and real-time neurorehabilitation.
Patients with disorders of consciousness, ALS, ADHD and other neurological conditions may show involuntary movements, short attention spans, fatigue or limited recording time, so fast preparation and reliable EEG acquisition are essential. Pre-mounted g.GAMMAcaps connect within seconds; the light wireless design improves patient comfort, reduces cable artefacts and makes reliable bedside assessments possible.
Recording EEG simultaneously with transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) lets researchers study cortical excitability, functional connectivity, neuroplasticity and the immediate effects of non-invasive brain stimulation at millisecond resolution. Dedicated algorithms in g.BSanalyze remove TMS and tDCS stimulation artefacts automatically within milliseconds.
Understanding audience engagement takes objective data beyond questionnaires; EEG measures attention, emotional engagement, cognitive workload and user experience at millisecond resolution. According to g.tec, Dolby Laboratories uses g.Nautilus Pro Flexible, combining wireless EEG with heart rate and skin conductance, to study audience responses to audiovisual content.
OSCAR LIVE demonstrates real-time artefact correction with g.Nautilus Pro Flexible and g.SAHARA Hybrid electrodes in dry mode: during increasingly demanding exercises, 16-channel wireless EEG is recorded while strong EMG, EOG and movement artefacts affect the raw signal, and the software corrects them in real time while keeping the relevant EEG information. OSCAR LIVE is included in g.HIsys Professional; OSCAR PRO, for offline correction, in g.BSanalyze Professional.
Eyes closed, blinking, head shaking, jumping, arm raising, push-ups, handstands, running and backflips: real-time artefact correction as the movement grows more intense.
Cleaning the cap correctly maintains clinical hygiene standards and extends the device's life. g.tec's official step-by-step guide to cleaning the EEG cap safely.
The modular architecture separates the reusable wireless amplifier from interchangeable electrode strands. Each strand carries 8, 16, 19 or 32 EEG electrodes configured with g.SAHARA Hybrid dry electrodes, g.SCARABEO wet electrodes or Safety Connectors for additional physiological sensors. Clinicians disconnect one strand and attach another, so one system supports different electrode technologies, patient groups, cap sizes and multimodal set-ups. That shortens preparation, simplifies cleaning and improves efficiency across patient groups and cap sizes.
