Modulating electrical current using nanotubes

from the nanodimmer-switch dept.
Foresight's Tanya Jones writes "(Reported by Science Daily) Researchers at NC State and UNC have discovered that turning a carbon nanotube may act as a dimmer switch to regulate the flow of electric current. Dr. Marco Buongiorno Nardelli, a research associate in physics at NC State, says being able to do this gives nanoscale-device designers a controllable, continuous means of converting mechanical signals into electrical signals.
