multielectrode arrays

[Eugen Leitl]

Anyone here working with DIY MAEs? http://en.wikipedia.org/wiki/Multielectrode_array

I'm looking into recording a few channels from

(scale bar is 1 mm) but can't afford used or refurbished MAEs.

I'm thinking about something like http://www.piclist.com/techref/pcb/direct-inkjet-metal-traces.htm
on a microscope slide, based on silver or platinum salts,
then baking and build a polymer ring wall you can put
a cap on.
