Manufactured into artificial engines from super cheap plastic fibers

An international team of scientists has successfully created an artificial muscle made of super-cheap plastic fibers.

According to research results published in the American Journal on February 20, the material that scientists use to make artificial muscle is polymer fiber - a kind of super durable chemical fiber with a diameter of 10 times the fiber. Hair, widely used in garment industry and fishing line making.

With this material, the cost of producing artificial muscle is greatly reduced compared to a current made of nickel and titanium alloy. Artificial muscle from plastic fibers is only priced at 5 USD / kg compared to the price of 3,000 USD / kg of alloy-made muscle.

Constructed by a method that has been successfully used by scientists, it is twisting strands like the way braided ropes, artificial muscles from plastic fibers perform functions and have strong forces similar to those of alloyed muscles. .

According to scientists, muscles from plastic fibers can lift an object that weighs about 7.3kg, while a set of hundreds of artificial fibers from this fiber has a lifting capacity of up to 800kg.

This newly built muscle can shrink by about 50% of the length, while a human muscle can only shrink by 20%. Artificial mechanics can be used as a new generation engine of robotic arms, aircraft wing parts, medical devices .

Previously, world scientists have also built artificial carbon-fiber mechanical devices by twisting rope.

This new invention was researched and developed by scientists from the University of Texas (USA) and research institutes in countries such as China, Canada, Turkey, Australia and Korea.
