Tiny FM Transmitter uses Voltage Controlled Graphene Resonator
A team of Columbia Engineering researchers, led by Mechanical Engineering Professor James Hone and Electrical Engineering Professor Kenneth Shepard, exploring the properties of graphene have demonstrated a new electro-mechanical resonant component.
The resonator’s structure consists of a 2-4 micrometer long strip of graphene suspended over a metal gate electrode. The strip of graphene has a natural resonance governed by its physical dimension and is used in the demonstration as the frequency determining element in an RF feedback oscillator circuit. Applying a voltage to the gate electrode stresses and deflects the graphene strip changing its resonant frequency. The team applied baseband audio and tones to the gate electrode to produce a 100 MHz FM signal.
This tiny resonant element looks set to dramatically reduce the size of mobile RF equipment. Traditional discrete quartz crystals have a relatively large PCB footprint but this resonator design will allow it to be integrated within the chip. To test it under extreme conditions the team played the now classic K-pop song ‘Gangnam Style’ on an iPhone and fed it into the graphene FM oscillator. It didn’t break although many wished otherwise. They were able to pick up the signal on an FM radio that Hone had brought in from home.
Timothy – So, the wireless signals that seem to be everywhere these days – are they there to power up these micro and nano scale electronics? FWIW I think you are right on the money. A few years back I extracted a strange looking critter from my arm. The thing looked like a flesh colored “M&M” but had what looked like a camera mounted on it’s top, complete with a cable running down it’s “back”. The left appendage was a small clamp while the right one looled like a drill(!). I know people who know people who know people, you know? (such is life on the internet world) so one person sent the image to another who sent it to a friend who works at one of the foremost labs in the ‘states. She said that it was an “MME” .. A micro-mechanical electronic device…. go figure…
hang in there man.
