Kimani Toussaint: Storage breakthrough with nano piano

/ / News, Publications, Recent Posts
Kimani Toussaint led research at the University of Illinois at Urbana-Champaign that demonstrates the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.

To demonstrate its abilities to store sound and audio files, Toussaint and fellow researchers created a musical keyboard or “nano piano,” using the available notes to play “Twinkle, Twinkle, Little Star” (listen below).

“The chip’s dimensions are roughly equivalent to the thickness of human hair,” he says.

Nano piano concept: Arrays of gold, pillar-supported bowtie nanoantennas (bottom left) can be used to record distinct musical notes, as shown in the experimentally obtained dark-field microscopy images (bottom right). These particular notes were used to compose ‘Twinkle, Twinkle, Little Star.’
