all elastic materials I know progressively lose their elasticity and stop returning completely back to their original position.
Hmm interesting. The ones I've found so far appear to be too thick. Can you give me a link, perhaps on ebay of the cable you are talking about.

In the radio control world, you can purchase tubing and small diameter steel cable that is meant to allow you to route the motion of a servo for longer distances (and to keep the moving parts out of the elements). Basically all you need is some small diameter plastic tubing, and the cable.Or, how about this:Run two lengths of mono-filament fishing line down plastic or vinyl tubing to the "base" of the finger mechanism. Route the fishing line to the finger such that one line pushes, and the other pulls to move the finger. Attach the other end of each line to the ends of one of the bar-linkage control horns (it looks like a "bar" with holes, and one central hole in the middle that attaches to the servo). This way, you can keep things fairly compact, and you only need a single servo for each finger.
