Cast Stretchy Traces

So far unsuccessful attempts at casting conductive traces by mixing various ratios of conductive paints (copper, silver, carbon) with latex. Applying them to a surface, letting htem cure and then peeling them away.
The following examples, while they look great, hardly conduct at all. Mixing even only a little latex into the water based silver paint seems to render it highly resistive.

Materials and tools

Applying water based silver paint mixed with latex to a already cured thin patch of latex.

After it cures, everything is stretchy, translucent and durable, but sadly not conductive.

Stretches beautifully, but does not conduct.

Even less successful attempts with copper paint and latex blends.

Pure copper (and water) not mixed with latex before casting with latex substrate. Cracks badly (of course).
