Scientists Create Artificial Muscles From Fishing Line

A team of researchers have developed a way to create artificial muscles by using just coiled fishing line and sewing thread, according to a recently published study.

International researchers like University of British Columbia Electrical and Computer Engineering professor John Madden and PhD candidate Seyed Mohammad Mirvakili, were able to detail how they created the artificial muscles capable of a generate more force and power than a normal human or animal muscle approximately the same size in the study.

The study was published in the journal Science this week.

In the study, Madden said that they found the artificial muscle is capable of lifting weights of 100 times more than a same-sized human muscle is capable of lifting, and generating the same power per unit weight as a jet engine.

"The simplicity is the beauty of this technology," said Ray Baughman, a chemist at the University of Texas at Dallas and leader of the study, according to LiveScience. "High-school students in their family room can make their own muscles and deploy them."

Researchers were able to make the muscles simply by twisting and coiling high-strength polymer fishing line and sewing thread. Twisting fiber creates an artificial muscle that's also able to drive a heavy rotor at speeds of 10,000 revolutions per minute.

The fiber muscles could be used to power the muscles in humanoid robots or exoskeletons, according to Baughman.

"Present humanoid robots or exoskeletons or prosthetic limbs are primitive, mechanically," Baughman told Live Science.

The artificial muscles could be used to open and close heavy windows in a building to regulate air temperature, without electricity or motors, according to the study.
