The mini thermometer, capillary temperature can be obtained

There's a big, wide world out there, and have the largest maximum thermometer, they invented the youngest, the mini thermometer. It is invisible to the naked eye, even the smallest thermometer read value, to using an electron microscope. The minimum thermometer was invented by researchers in Japan material research institute, also known as & other; Carbon nanotubes thermometer & throughout; 。 The thermometer is used less than 1/500 of a human hair in diameter of the tubular carbon nanotubes, by filling of liquid gallium at about 1/1000 of a millimeter in length, diameter of carbon nanotubes is only 1/10000 of a millimeter. When the temperature rises, the tube in the liquid gallium will expand, can read the temperature value, through an electron microscope can temperature measurement. The smallest is the measuring range of the thermometer 18 & deg; — 490° , the temperature down to 0. 25° , can be used to check whether the electronic circuit is abnormal, also can be used to measure the temperature of the human body blood capillary, can also be used in other ways.
