Translation: sheets of entirely flexible, waterproof, implantable LEDs. Yes, yes, medical and biotech applications, but imagine how interesting the tattoos at raves will be in a few years!
From Scientific American’s writeup:
As a demonstration of the technology the researchers put LED arrays through any number of experimental implementations. They deposited LEDs on aluminum foil, the leaf of a tree, and a sheet of paper; they wrapped arrays around nylon thread and tied it in a knot; and they distended LED arrays by inflating the polymer substrate or stretching it over the tip of a pencil or the head of a cotton swab. “Eventually the students just got tired” of devising new tests for the light-emitting sheets, Rogers says. “There was nothing that we tried that we couldn’t do.”
