[Eeglablist] active electrodes

Any and all:

FDA clears devices for general safety and efficacy for clinical use in the USA but does not care about research use. UL/CSA/ETC etc. certifies electrical safety specifically. You are covered legally for research use by your institutions IRB process, which should address the electrical safety issue and not care about FDA or clinical use.

In Europe I believe the CE regulates devices for general safety and efficacy, as well as electrical safety specifically, combining the roles of FDA and UL.

Many EEG systems are sold in the USA with FDA clearance for clinical use and that have up to 256 channels with electrode caps or nets that use variants of the 10-20, 10-10, or 10-5 system, or uniform geodesic spacing as the EGI produces. Some of these have active electrodes. Now it may be the case that the FDA does not clear any active electrode system for clinical use in the USA, but that has no impact on using them for research, as your IRB should take care of assuring their electrical safety.

Dear Doron,

Interesting topic. I heard a rumor that the FDA-approved EEG recorder in US (I don't know which) supports only the classical 10-20 system channels... I could be wrong though. Anyone on the list please tell us what you know about this. I'm curious to know too. Thank you.

This is not directly related to EEGLAB but perhaps of interest to many of us: my understanding is that none of the devices with  active electrodes have any standard approval, such as CE (Europe) or FDA (US). Does that mean all of us who are using them in research labs are not covered legally? And what about commercial applications, such as neurofeedback?
