FLEXIBLE EEG DESIGNED FOR CLINICAL EEG WORKFLOWS
Designed for modern clinical workflows with fast patient preparation, interchangeable dry, wet, and hybrid electrode strands, simplified infection control, and reliable wireless EEG acquisition for hospitals, rehabilitation, and clinical neuroscience.
WEARABLE EEG SYSTEM DESIGNED FOR CLINICAL WORKFLOWS
Clinical EEG requires more than high-quality brain signal acquisition. Healthcare professionals need fast patient preparation, reliable recordings, flexible electrode configurations, and efficient cleaning between consecutive examinations. The g.Nautilus PRO Flexible was developed specifically for these clinical workflows, combining research-grade EEG performance with a modular design that simplifies everyday use in hospitals, rehabilitation centers, and clinical research environments.
The wearable EEG system supports 8, 16, 19, or 32 channels and allows users to exchange complete electrode strands within seconds while using the same amplifier. Depending on the application, clinicians can choose g.SAHARA hybrid dry electrodes, g.SCARABEO wet electrodes, or Safety Connector strands for additional biosignal sensors. This flexibility enables one amplifier to support different electrode types, cap sizes, patient populations, and recording protocols without changing the acquisition hardware.
Unlike conventional EEG systems, the removable electrode strands can be cleaned, disinfected, and exchanged independently of the amplifier. This significantly simplifies hygiene management, reduces turnaround time between patients, and supports efficient workflows in clinical environments where multiple recordings are performed every day.
Whether used for clinical EEG, neurorehabilitation, disorders of consciousness, epilepsy research, EEG-TMS, EEG-fNIRS, or mobile neuroscience, g.Nautilus PRO Flexible provides a flexible, reusable, and future-proof platform that adapts to changing clinical and research requirements.

“We have several ongoing studies. One of these studies is to extend human arm control to new approaches that control more than two arms with the help of brain-computer interfaces.”
Hiroshi Ishiguro, PhD - Intelligent Robotics Laboratory, Japan
“g.Nautilus wireless EEG amplifiers allow us to investigate freezing of gait in Parkinson’s disease, a dangerous symptom for the aging population as it can lead to falls. We can synchronize the EEG signals with VICON motion capture data seamlessly, without adding extra burden on our patients such as backpacks, or wired in hardware following them.”

The g.Nautilus PRO Flexible can simultaneously record EEG and additional physiological signals using the Safety Connector strand. Connect EMG, ECG, EOG, GSR, respiration, temperature, pulse, blood pressure, and other biosignals to create synchronized multimodal recordings for clinical assessments, neurorehabilitation, Brain-Computer Interface applications, and neuroscience research. The modular design allows researchers to configure the recording setup for each study without changing the amplifier, providing one flexible platform for multimodal neuroscience and clinical research.
NEUROREHABILITATION
Neurorehabilitation requires reliable EEG recordings while patients perform natural movements during therapies such as upper-limb rehabilitation, gait training, motor imagery, and Brain-Computer Interface training. The lightweight wireless g.Nautilus PRO Flexible minimizes cable-related artifacts, allowing patients to move more naturally during recording sessions.
g.GAMMAcaps with pre-mounted electrode strands enable fast patient preparation and consistent electrode placement, while the removable strands simplify cleaning between therapy sessions. Combined with the g.tec software ecosystem, g.Nautilus PRO Flexible supports stroke rehabilitation, motor recovery research, and real-time neurorehabilitation applications.
BRAIN ASSESSMENT FOR DISORDERS OF CONSCIOUSNESS, ALS & MORE
Patients with disorders of consciousness (DOC), amyotrophic lateral sclerosis (ALS), ADHD, and other neurological conditions often present significant challenges for EEG acquisition due to involuntary movements, limited attention spans, fatigue, or restricted recording time.
The g.Nautilus PRO Flexible was developed for demanding clinical workflows where fast preparation and reliable EEG acquisition are essential. g.GAMMAcaps with pre-mounted electrode strands connect within seconds for rapid patient setup and consistent electrode placement. The lightweight wireless design improves patient comfort, reduces cable-related artifacts, and enables reliable bedside brain assessments and neurorehabilitation with the complete g.tec clinical software ecosystem.
SIMULTANEOUS EEG, TMS AND TDCS
Simultaneous electroencephalography (EEG) with transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) enables researchers to investigate cortical excitability, functional connectivity, neuroplasticity, and the immediate effects of non-invasive brain stimulation with millisecond temporal resolution.
The g.Nautilus PRO Flexible supports wireless EEG acquisition during TMS and tDCS experiments. Combined with g.BSanalyze, dedicated post-processing algorithms automatically remove TMS and tDCS stimulation artifacts within milliseconds, enabling reliable analysis of brain activity after stimulation. This makes the platform well suited for neuromodulation research, cognitive neuroscience, neurorehabilitation, and closed-loop Brain-Computer Interface applications.
