Toward the World's Smallest Radio

Toward the World's Smallest Radio
A graduate student of the University of California-Irvine demonstrates world's first working version of a carbon nanotube radio system. A report on this amazing device appeared in Nano Letters, one of the American Chemical Society's 36 peer-revewed scientific journals. This video was among supporting materials for the research paper.
Peter Burke and Chris Rutherglen developed a carbon nanotube "demodulator" that is capable of translating AM radio waves into sound. In a laboratory demonstration, the researchers incorporated the detector into a complete radio system and used it to successfully transmit classical music wirelessly from an iPod to a speaker several feet away from the music player. Nano is short for "nanometer," and that means small, so small that thousands of the carbon nanotube radio devices would fit across the diameter of a human hair.

looks like a bunch of shit you bought at a yardsale

[ToadHypno]

People just dont get the significance of this...good work man, we will see a roll up plastic computer sooner than you think.

[MrDavidJWatts]

Awesome!

[anonysquirrel]

That's similar to a crystal radio that uses a diode detector instead of a nanotube. The crystal radio is simpler, because the diode does not have to be biased.

Sounds like he needs to do an article for the midnightscience site-- it's all about crystal radios, which only sometimes need a bias to work.

Incredible!

thats my 4th grade teacher's son! Ms. Rutherglen told me about his video.

[sirnicholson]

laugh out loud.you have created an exsploded version of a radio

[Isosphere]

Amplitue modulated, I guess.

[undergroundman1993]

It sounds awesome, and I loved the scientific grade cookie sheet.

You might wanna try doing a literature review first next time buddy. I suggest you start with "Cats Whisker"
