Comparison of Greentek & Biosemi Active 2 & g.Nautilus Multi-Purpose & Tenocom EEG caps

Last Updated on January 8, 2024 by pg@petergamma.org

greentek sleep EEG cap:

length of instructional video: 2 minutes

number of papers with greentek sleep EEG cap on Google Scholar:

https://scholar.google.com/scholar?hl=de&as_sdt=0%2C5&q=greentek+sleep+EEG+cap&btnG=

we did not find any.

The video shows an example of 5 seconds where the sleep cap has an EEG signal which has no issues. Are there any examples which proof that it runs longer without issues?

Biosemi Active 2 EEG cap

length of instructional video: 30 minutes

paper with the Biosemi Active 2 EEG cap on Google Scholar:

https://scholar.google.de/scholar?hl=de&as_sdt=0%2C5&q=biosemi+active+two+cap&btnG=

We did not count the number of papers, there are too many.

g.Nautilus Multi-Purpose EEG Headset

length ofr product configuration video: 10 minutes

costs: 50 000 USD

setup time: unknown

paper on Google Scholar with g.Nautilus” Multi-Purpose EEG Headset”

https://scholar.google.com/scholar?hl=de&as_sdt=0%2C5&q=g.Nautilus+Multi-Purpose+EEG+Headset&btnG=

9 papers.

Still we are looking for an EEG cap with for instance semi-dry EEG electrodes such as the g.tec multi-purpose EEG headset has which can be set up quickly and does not cost 50 000 USD.

Tenocom EEG caps

length of instructional video: 2 min 56

papers on google scholar:

https://scholar.google.com/scholar?hl=de&as_sdt=0%2C5&q=tenocom+eeg+cap&btnG=

2 papers:

starting prize: 70 USD

price we found later on 700 USD.

This is a sign that Tenocom does stock market speculations with EEG caps and increases prices if positive feedback are given. We suggest therefore not to mention Tenocom EEG caps anymore.
