It is known that intense sound can be produced by electrically-powered nanotubes stretched into sheets, but researchers from University of Texas at Dallas (UT Dallas) have furthered this principle by arranging sheets of carbon nanotubes into “forests” which produce high-quality sound when struck with lasers. This is an exciting advancement in the field of acoustics since it is thought these forests could be used to form invisible wireless speakers that could be embedded into walls, windows, computer screens, cars – the list is endless. ..
