Hi Michael,
I am interested in silver/silver-chloride electrodes like the ones
seen here:
http://www.electrodestore.com/EEG/EEG-p13.html
Some important points:
* The inner surface of the electrode must be free from scratches.
* The electrodes should be designed so that no other metals except
the silver comes in contact with the electrolyte as they are
rechloridized. The chloride coating would otherwise be contaminated
by other metals, such as lead or copper.
Regards,
Andreas
