Graphene origami as a mechanically tunable plasmonic structure for infrared detection
Researchers have successfully developed a tunable infrared filter made from graphene, which would allow to change the frequency of a filter simply by controlled mechanical deformation of the filter (i.e., graphene origami), and not by replacing the substance on the goggles used to filter a particular spectrum of colors.
