Carbon Nanotubes for Loudspeakers

Nanotechnology labs around the world do love to experiment with carbon nanotubes, often offering up some rather peculiar contraptions made out of the wonder material like the â''Nano Radioâ''.

But these lab curiosities are often just examples of what can be done with carbon nanotubes, theyâ''re not really intended to lead to commercial products.

But the latest one described in the October 29, 2008 online edition of Nano Letters and further detailed over at Nanowerk does seem to have commercial aspirations.

Dr. KaiLi Jiang, an Associate Professor in the Department of Physics & Tsinghua-Foxconn Nanotechnology Research Center at Tsinghua University in Beijing, and his collaborators see commercial possibilities for the carbon nanotubes loudspeakers they have developedâ''a demonstration of which can be seen in the video below.

While Jiang believes that the technology might create applications not yet considered, one that has been proposed would "be laptop computers where the current audio system could be replaced simply by putting a transparent loudspeaker film over the display area".

Unfortunately, in the same Nanowerk article in which this application is proposed the next sentence offers up â''application in revolutionary new design concepts for tomorrow's electronics such as the Nokia Morph mobile phoneâ'' as a viable commercial usage.

Iâ''ve heard on fairly good authority that few involved in the Morph project were looking at a commercial product as much as they were looking for a way to demonstrate the advancements in plastic electronics. Better to leave that particular â''future applicationâ'' off your list.
