Well, actually, it's graphene, but they've treated it to fold when exposed to heat. (Not dissimilar from thermoplastics sometimes used in theatrical and cosplay props).
They're saying that this might be useful in artificial muscles (for lighter prostheses) and smart clothing that changes its shape according to the heat. (Imagine sleeves that roll themselves up when the temperature hits a certain preset level).
And yes, the word "origami" has come up.
