Hi,

I am setting up a new EEG lab and we have the possibility to ask for a conductive floor (ESD flooring like for IT/server rooms). Is that helpful for measurements with a BioSemi EEG system?

My intutition is that it would be great to prevent electrostatic charging of the participant, but on the other hand it would connect the participant to the building's ground which might have some noise itself. Furthermore, it could be a sink for DRL and thus interfere with the floating ground of the EEG system. Is it correct that this would then have an adverse effect on EEG signal quality?

Any advice would be appreciated.

Best,
Sebastian

The ESD floor has a high resistance (MegaOhm to GigaOhm) and would not make any difference to the interference rejection of the BioSemi system.

The inputs of the BioSemi system are protected against static discharge (standard EN 61326). An ESD floor is not required to prevent damage. Just remain careful with the usual sources of static: fleece sweaters are infamous in this respect.
