Melody Encoded onto Plasmonic Nanostructure
CHAMPAIGN, Ill., March 17, 2015 — With data storage capacity 5600 times greater than magnetic film, a chip made of tiny gold bow ties could be the next best place to store all your MP3s.
Researchers from the University of Illinois at Urbana-Champaign recently created the first-ever optically encoded audio recording using a plasmonic nanostructure. Using the device as a “nano piano,” they were able to input and then play back the melody of “Twinkle, Twinkle, Little Star.”
