Columbia engineers make world's smallest FM radio transmitter
Date:11/18/2013

New York, NYNovember 17, 2013A team of Columbia Engineering researchers, led by Mechanical Engineering Professor James Hone and Electrical Engineering Professor Kenneth Shepard, has taken advantage of graphene's special propertiesits mechanical strength and electrical conductionand created a nano-mechanical system that can create FM signals, in effect the world's smallest FM radio transmitter. A team of Columbia Engineering researchers, led by Mechanical Engineering Professor James Hone and Electrical Engineering Professor Kenneth Shepard, has taken advantage of graphene's special propertiesits mechanical strength and electrical conductionand created a nano-mechanical system that can create FM signals, in effect the world's smallest FM radio transmitter. The study [http://dx.doi.org/ - DOI 10.1038/nnano.2013.232] is published online on November 17, in Nature Nanotechnology.

"This work is significant in that it demonstrates an application of graphene that cannot be achieved using conventional materials," Hone says. "And it's an important first step in advancing wireless signal processing and designing ultrathin, efficient cell phones. Our devices are much smaller than any other sources of radio signals, and can be put on the same chip that's used for data processing."

Graphene, a single atomic layer of carbon, is the strongest material known to man, and also has electrical properties superior to the silicon used to make the chips found in modern electronics. The combination of these properties makes graphene an ideal material for nanoelectromechanical systems (NEMS), which are scaled-down versions of the microelectromechanical systems (MEMS) used widely for sensing of vibration and acceleration. For example, Hone explains, MEMS sensors figure out how your smartphone or tablet is tilted to rotate the screen.

In this new study, the team took advantage of graphene's mechanical
