Might it take the place of the liquid metal (pseudomulti alloy) generated publicity with the preceding crop, and the invention of Mr. Ray Baughman's laboratory appear in a next work of 'Terminator'.
It is "Muscle of the next generation" that can be done in the carbon nanotube.

Mr. Baughman's team succeeded in the production of the material that was stronger than steel, lighter like air, more flexible than rubber that was able to be called the muscle of the 21st century exactly.
..robot.. in addition, if you use this ..the super-strong ..the artificial limb and "It is smart" coating film.. ..the shape change.. ..the structure....――In the future very near――A highly effective solar cell etc. might be able to be made.

Mr. Baughman who serves as the accountable person in the University of Texas at Dallas nanotech laboratory speaks, "About 30 times power for each unit area can be exerted compared with the living body muscle".

After the research of the carbon nanotube starts at the beginning of the 1990's, the molecule of the cylindrical with extremely high strength has continued to enchant the material scientists by this ultra-lightweight. The carbon nanotube is still used for the material such as the ropes with the possibility to be used for the cable of the experimental model of parts of the bicycle and aircraft, the flak suits, transistors, and the space elevators of the future (Japanese version article) already, too though the development of a commercial usage is late because mass production is difficult.

It uses that Mr. Baughman was interested in the carbon nanotube the electroconductive polymer.
It is time when tried to make the artificial muscle. This Mr. noticed the one that the carbon nanotube tied from the polymer go well use. Then, first of all, the nanotube fiber intertwined disorder was moved by using a charged liquid.
Next, it experimented by the array that there is a consistency in the composition or more, and, in addition, the charge was given by the method besides last time.

The artificial muscle material that Mr. Baughman this time developed is the one announced with the thesis published in the title on March 20 of the 'Science' magazine (United States time). It orients vertically, and it consists of the bunch of the nanotube that reacts directly to electricity.
It longitudinally extends, it shrinks by a highspeed extremely, and there is a possibility that this muscular material to which strength extremely is exerted can be applied to various usages as long as the engineer may imagine it in horizontal direction.

Material scientist John Madden of British Columbia University is describing in the accompanying commentary, "It is near this feeling that aeolotropic at the unprecedented level (physical property that depends on the direction) still shows the character like the diamond in the a certain direction and shows a rubbery character in another direction perhaps".

The carbon nanotube fiber repulses and attracts Mr. Baughman's artificial muscle by the array in using the trend of the charge each other.
When it is 10% of the the greatest a second, the living body muscle contraction rate is Iu according to Mr. Baughman.
The nanotube material that this Mr. developed boasts of the shrinkage factor of 40,000% a second compared with this.
It is far more efficient than what designed before that because it reacts from the ionic migration in the electrolyte to the current.

Moreover, this nanotube material keeps the character under a wide temperature in the centigrade from a minus centigrade 196 degrees to 1538 degrees that are the melting points of iron that are the boiling points of liquid nitrogen.
Mr. Baughman described the first usage of this material that the possibility of becoming the protection material of the solar cell was high.
It is because shape is quickly changed to make conducting electricity of the nanotube, and the most suitable array for the exposure.
