NAUTILUS MULTI PURPOSE

WEARABLE EEG HEADSET

The g.Nautilus Multi-Purpose version allows you to acquire both EEG and other biosignals along with data recorded simultaneously from 4 detachable channels, which can connect to other sensors such as ECG/EOG/EMG electrodes or sensors to measure GSR, respiration, and many other signals. This version is available with dry or gel-based EEG electrodes, both of which allow flexible positioning.

SPORTS SCIENCE AND MEDICINE

If you’re interested in sports applications, you need a wearable EEG headset that is lightweight and highly robust to movement and challenging real-world environments. g.Nautilus weights about as much as a climbing carabiner and has very compact packaging. The dry EEG version is well suited for high-altitude medicine because it does not require any hair washing, which is difficult in remote locations. For many sports, very good contact between the head and the electrode is crucial, and hence we recommend the gel version for these applications. If the g.Nautilus is well prepped with gel, people can even jump and run without seeing artifacts in the data.

UNLIMITED POSSIBILITIES

Wearable EEG and biosignal acquisition headsets are becoming increasingly important in medical and clinical environments, especially since more and more studies are conducted in the field instead of the lab. Therefore, g.tec developed g.Nautilus. Its design is completely different from all other devices, and it sets a new standard of usability. The tiny and lightweight device is attached to the EEG cap to avoid cable movements and to allow completely free movements. In combination with dry or gel-based active EEG electrode technologies, users get top quality EEG recordings from 8-64 channels within few minutes.

MEASURE BIOSIGNALS IN THE MOUNTAINS

During alpine expeditions, g.Nautilus can be used to measure the effects of high altitude on both EEG and ECG parameters. This is especially interesting for altitude medicine research.
