Are there any viable replacements for Indium-Tin Oxide electrodes?

I am looking to obtain a metal oxide ceramic that can be synthesized from a Sol-Gel procedure that is both conductive and flexible. Indium-Tin oxide does apply in this case, however the cost of Indium, combined with the fact that Indium-Tin oxide is more of an alloy, does not make it viable. Transparency is not an issue for this application.
