Flexible Hologram Changes when Streched

Flexible Hologram Changes when Streched
Researchers have developed the first stretchable hologram, opening the door to a new display that changes the displayed information as it is stretched.

The stretchable hologram was made possible by a metasurface created by a team at the University of Pennsylvania. Using a computer calculation to determine the correct pattern, the team created a network of gold nanorods and embedded them in the flexible polymer PDMA via an etching and layering process. They then created a hologram with more than one image appearing at different distances from the surface of the material, so that when the material is stretched, the holograms seem to morph into view.
