Playing Nanoguitars
Posted on Wednesday 29 October 2003 to Frontiers
This 10-micron-long guitar, built at Cornell University in 1997, has only now
been played for the first time.
Cornell researchers used laser light to
set the delicate silicon "strings" (actually slender planks of silicon)
of the guitar in motion. The strings vibrated at a frequency of 40
megahertz, some 17 octaves (130,000 times) higher than a normal guitar.
Now all they need is a nano-microphone to hear it.
