[Eeglablist] dry electrodes

[Bluhm, Juergen]

Hi guys,
We have very good experiences with dry electrodes, especially in market research studies, due to the easy setup and the same data quality even over longer periods of measurements. But we only need a few channels, so this may limit the use for others, but in our research field it is a big improvement over the wet electrodes we had to use before.
Cheers,

Hi Ettore,

Dry electrodes are very common these days, because they greatly facilitate data collection. However, there can be great SNR loss depending on the headsets. There are also various hardware differences that can impact the signal. There is tons of resources online on this topic, for example:
