An international team of scientists from the United States, China, Australia and other countries has successfully made use of ordinary fishing thread and sewing thread to create 'artificial muscle'. They even think that the intelligent fabric made of this' artificial muscle 'could be used to make armor like iron man in the future.
The research was published in the journal Science on the 20th. Fang Shaoli, an associate professor at the University of Texas at Dallas and Li Na, a postdoctoral researcher who participated in the study, told Xinhua that the key to this kind of artificial muscle is to produce a kind of spiral structure of spring. The most important function of muscle is to produce strength through contraction, and this spiral structure of 'artificial muscle' can produce very good contraction effect.
According to the introduction of this kind of artificial muscle. The contraction rate of human muscle is only 20%, while the contraction rate of this kind of 'artificial muscle' can reach 50%, and it is stable and lasting. Its lifting capacity is about 100 times that of human muscle of the same size and weight.
This kind of artificial muscle also has strong machinability. It can enrich the facial expression of the robot and make the minimally invasive microsurgery instrument more flexible.
Professor Wang ce of Jilin University in China, who participated in the research, told reporters that the material can expand and shrink with the change of ambient temperature. Therefore, the blinds made of this kind of artificial muscle can automatically open when it is hot and close automatically when it is cold. The fabric made of it can realize the automatic control of pores. In the future, people can use it to make clothes that can automatically adjust, and even make protective armor. He thinks: 'this kind of & lsquo; artificial muscle & nbsp; is still expected to be used in aerospace, military, medical and other fields in the future. '
