g.Nautilus: Specs & Features

Wireless Biosignal Acquisition System

g.Nautilus - g.tec's wireless EEG system with active electrodes

g.Nautilus is g.tec’s new wireless biosignal acquisition system. 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 g.tec’s active electrode technology, you will get top quality EEG recordings from 64/32/16/8 channels within few minutes. Just put on the cap, add a bit of gel in each electrode, and start your recording. A dry electrode version based on the worldwide proven g.SAHARA electrodes is also available. g.Nautilus has a built-in lithium ion battery, which allows for continuous recordings of up to 10 hours. The battery is recharged via a contactless charging pad within 2-3 hours. The device is completely waterproof, which allows easy cleaning of the electrodes together with the cap, with no need to disconnect or disassemble anything! g.Nautilus transmits data via the 2.4 GHz band with an indoor operating range of about 10 m. The input sensitivity of all channels is adjustable and the sampling rate can be set up to 500 Hz (250 Hz with the 64 channel version). An electrode impedance check can be performed automatically via software, and a 3-axis acceleration sensor provides online head movement information along with the biosignals.

The base station for g.Nautilus is just a small receiver box connected to the PC via USB. 8 digital trigger lines can be connected to the base station to record event timing information. g.Nautilus comes with a 64-channel EEG setup (10/20 system), but subsets with different electrode arrangements are available on request.

g.Nautilus is available with flex-print connectors or with cables, which allows flexible positioning of the electrodes on the whole cap. We provide g.Nautilus for research purpose but we have also CE certified medical devices (g.Nautilus PRO) available.

Pricing for g.Nautilus starts at 4500 Euro.

EXPERT QUOTES

"The g.Nautilus allows my participants to interact more freely in our experimental environment, since they finally are untied from the amplifier."

 - Dr. Robert Leeb, CH

“With the g.Nautilus system our research group has managed to combine the BCI technology with other intelligent systems without expending time on replicating laboratory conditions everywhere to obtain good quality signals. Now we believe it’s possible to have computers, robots and smart devices interacting with a BCI in places where just a few years ago it was technically infeasible.”

 - Omar Mendoza Montoya (Freie Universität Berlin)

"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."

 - Dr. Aysegul Gunduz (University of Florida), US


EXPERT QUOTES

"We have used the g.USBamps for approximately four years now and the quality of the signals surpasses our greatest expectations. Last year we also invested in the g.Nautilus system and have been able to move from the more stringent laboratory conditions to the real world settings where BCIs find their applications. I would highly recommend both for anyone involved in BCI research.“

 - Associate Professor Natalie Mrachacz-Kersting,
   Aalborg University, DK


g.Nautilus sports application

Clean signals as a quality feature

The g.Nautilus sports measurements show how the wireless g.Nautilus biosignal amplifier can record EEG signals during sports activity and other exercises. From the raw EEG signals, Auditory Evoked Potentials (AEP) can be derived, which can show how physical motion like spinning or running impacts the subject’s ability to concentrate on mentally counting the acoustic stimuli. The g.Nautilus system can record, process, and analyze AEPs and other biosignals in real-time. 

In the first picture (left), the user is spinning wearing a wired EEG cap, later the same experiment was done with the wireless EEG cap g.Nautilus as you can see in the other pictures. The test results show that the wireless EEG cap is not only convenient, but can also produce clean data without any noise and artifacts from physical movement or other sources. 

The raw data of the scope doesn't show many artifacts due to movement, since the g.Nautilus is a wireless EEG cap.
