So the thing about flexible technologies is that they don’t just have to survive bending, they also have to survive stretching and twisting: things we take for granted in living things, but which are harder to implement when we’re building without the benefit of millions of years of evolution.
So this work from Harvard on a material that can stretch, recoil, and repair itself is really neat. Possible uses include replacement cartilage, for bandages, and for lenses that act like the eye’s iris.
