Who is interested in Biosemi Active Two amplifiers which are sold from Neurospec in Stans in Switzerland? – PETER GAMMA (Director & Physiologist), MEDITATION RESEARCH INSTITUTE SWITZERLAND (MRIS)

In recent years Neurospec in Stans in Switzerland showed different YouTube videos about Biosemi Active Two amplifiers:

These demonstrations remind strongly to those of Krisztián Hofstädter:

The difference is that Biosemi Active Two amplifiers cost 10 000 USD for 8 EEG channels. We hope that Neurospec finds costumers for this devices among the Swiss Universities.

But Peter Gamma from www.petergamma.org is not interested in these, Since Peter Gamma thinks a 32 channel EEG device will sooner or later not be worth much more than 500 USD, if it is sold on Aliexpress and shipped directly to Switzerland:

What does dilute the business for EEG devices?

And we can add the Biosemi Active 2 amplifers to our comparison table as well.

	EEG device	architecture	EEG channels	costs (USD)
1	Biosemi Active 2	Device which was developed before the Texas Instruments ADS1299 chip has been released	8	10 000
2	OpenBCI Cyton + Daisy Biosensing Boards	Texas Instruments ADS1299	16	1800
3	EEG device built by Hugo Plácido da Silva	TGAM & Influxdb	16	estimated 500
4	EEG device built by Hugo Plácido da Silva	TGAM & Influxdb	32	estimated 1 000

And we highly appreciate Hugo Plácido da Silva for his contributions to lower the costs for physiological sensor devices:
