Bioinspired fibers change color when stretched — Harvard School of Engineering and Applied Sciences
Interesting photonic fiber research, which resembles dichroic materials, but because it is stretchable, allows active changing of the color by adjusting the bandgap. Possible uses in smart cloth showing deformation damage, or as a possible active camouflage textile system.

Tunable Electromagnetic Gateway : Light and Electromagnetics Blocked but Corridor is Filled with Air
I wonder if this could be used as a kind of magnetic field barrier that is porous to liquid nitrogen to cool a superconducting magnet or coaxial superconducting wire to cut down or contain the magnetic field which can be harmful to high temperature superconductor operations?
