Self-folding paper

Finishers take note: self-folding paper. This self-folding paper is made of graphene paper. How cool is that, instead of folding an origami crane, a self-folding origami drone. The graphene paper which researchers in China have developed changes its shape at certain temperatures. They build a number of active pieces in the material which react. By exposing it to infrared light the paper folds itself.
It seems to be possible to make an artificial muscle which is useful for artificial limbs. This material can move in a more natural way than a motor.
A self folding newspaper seems to be somewhat futuristic, but with a little imagination the possibilities seem endless.
