Scientist at the University of Texas in Dallas have designed super strong artificial muscles by simply twisting and coiling ordinary fish line.
The coil muscles can lift more than 100 times the weight of a human muscles of the same size and generate as much as mechanical per kilogram as a jet engine. Perhaps offering an inexpensive new material to move Prosthetics and robotic exoskeletons.
“There are many types of artificial muscles that have been talked about for many years”, said the study’s lead author Ray Baughman, director of the Alan. G MacDiarmid NanoTech Institute at the University of Texas at Dallas. “Very few are commercially used.”
Creating the muscles is simple. Researcher use a tool similar to a hand drill to twist different sizes of fishing line to the point of coiling. The twist allow the thread to function like a torsional muscle that can lift heavy loads.
Depending on the direction of the coil, the artificial muscles will expand and contract with temperature changes, which can be produced by electricity, water, light or chemical reactions of fuels.
For example, a homochiral muscle contracts when heated and expands when cooled. Coiled in the opposite direction, a heterochiral muscle will expand when heated and contract when cooled. Coiled muscles can spin a heavy rotor more than 10,000 revolutions per minute, or RPM, when uncoiling.
Researchers tested various widths of polymer coils using several techniques to activate expansion and contraction of the coils. They report these findings in Science.
There’s no telling what the future holds for the revolutionary tool in a lot of scientists’ tackle boxes. Fishing line: for more than just the big catch.
