Hi Brad,

ITO would be the way to go. You can go more conductive than that with
ITO without too many problems, on glass at least. The adhesion to
something like PI is probably good, but it depends on your plastic and
how adherent coatings are to it in general, as well as the roughness,
etc, as that can have an effect on adhesion and sheet resistance.

Subject: [mems-talk] Transparent conductive coating

Hi Everyone, and Happy New Year.

Is anyone aware of a service that can apply a transparent conductive
coating to a plastic sheet?  This would have to be fairly low
temperature process due to the low melting point of the plastic.  The
sheet resistance requirements are not too rigorous, anything under 400
ohms/square should be fine.  Optimally, it would need to be >99%
transmissive over 400-1100nm wavelength range, but at this point >80% is
acceptable.

Thanks for your help.
