Nanotube radio – world’s smallest: Can it be tied up to MEMS?
Posted by evolvingwheel on November 12, 2007
I love technologyreview.com. Whenever I visit after a while, I always find something enthralling. Something that just pokes my mind and ends up creating a boundless array of imaginative possibilities. This time I came across the article on world’s smallest radio – a carbon nanotube that is able to receive radio-frequency and play the song sent over the carrier wave.
Innovative engineering feat resides in the simplest perspective. When a complicated scientific phenomenon, in this case a radio, is condensed in a nanoscale dimension, the magic is worth watching. Even if there is no immediate commercial prospect of the invention, the concept itself is path-breaking. One of the coolest aspect of the research is the way the radio receives the signal. In conventional radios the antenna receives the electromagnetic signal. Over here the radio starts responding when the frequency of the carrier wave matches the resonating frequency of the carbon nanotube. You can find the detail in the link [here].
I was also reading about the possible applications. One of them worth talking about is the packaging of this radio with MEMS (microelectromechanicalsensors). MEMSare supposed to be injected into the bloodstream and the sensors will record data – blood sugar level, cancer markers, blood pathogens, etc. Once this radio is configured to transmit data, a whole new world will open up (may be already in the process of opening up). MEMS will play an enormous role in preventive diagnostics and this tiny radio can remotely send information to a receiver outside the body. I have to do some more research in biological MEMS now!
