Can anyone suggest me some material which is a perfect electrical insulator but becomes a perfect conductor when stretched to about two times of its length

H Chris Ransford

I doubt if such a material exists at all, but if you need this characteristic why don't you engineer one, perhaps on the basis of a dual composite ?
