Guinness calls Japanese thermometer world's smallest

TSUKUBA, Japan - The Guinness World Records book has named a thermometer (release photo) using a carbon nano tube as the world's smallest thermometer, its developer, the National Institute for Materials Science, said Dec. 3. The thermometer, developed by Yoshio Bando and another scientist at the government-affiliated institute in Tsukuba, Ibaraki Prefecture is a tube formed by carbon atoms. Measuring about 85 nanometers in diameter and several thousand nanometers in length, it can measure temperatures between 18 C and 490 C with a 0.25 degree notch. It can be used to measure temperatures in capillary blood vessels and detect abnormalities in computer chips. (Kyodo)

    TSUKUBA, Japan - Photo taken through an electronic microscope shows the world's smallest thermometer, developed by scientists at Japan's National Institute for Materials Science in Tsukuba, Ibaraki Prefecture. An article in the Feb. 7 issue of Nature magazine said Yoshio Bando and Gao Yihua applied nanotechnology to create the device, measuring just 10 micrometers, or about one-10th the diameter of a human hair, in length, by using a tiny carbon tube. Photo was provided by the institute.
