Nanotube Speakers

Published on April 9th, 2009 | By: pwray@ceramics.org
This video is about the novel use of carbon nanotubes as audio speakers. The first part of the video shows the transparency of
such a speaker. The second part is an illustration of the way the CNTs
create the sound by going through rapid heating-cooling cycles instead
of vibrations. The third part shows how the sound quality is unaffected
by stretching. Finally, the video shows a CNT speaker sewn onto a
small, waving flag.
