Twisted Carbon Nanotubes Can Be Used As Springs - New Technology

Researchers from the University of North Carolina at Chapel Hill have found that by twisting carbon nanotubes they will act as miniature springs for use in nanoscale devices.

By using an atomic force microscope and a scanning electron microscope they were able to place ‘paddles’ on a single nanotube and then use the paddles to twist it. The nanotube was shown to have stored the energy applied and stiffened by as much as twenty times.
