Nanofiber create artificial muscle 200 times stronger than human muscle

Nanofiber create artificial muscle 200 times stronger than human muscle

A team of researchers in Ohio has created small artificial muscles that are 200 times stronger than human muscle fibers of comparable size. A development that could mean in the future improved versions of muscles that could be taken in different areas. They ensure that the robots in the coming decades will come to grace human aspect to it.

The scientists behind the work are enthusiastic about what has been achieved. These possibilities have explained that open in the improvement of this type of material. Moving parts in robots or airplanes are always driven by motors. This is the reason that in recent decades has tried to advance the creation of artificial muscles that work in the most close to what muscles do naturally, it comes to look more delicate movements.

Ray Baughman, who led the team behind this new type of artificial muscle, commented on its development:

What we have built could be considered as a kind of thread because of the way in which it is woven. These muscles can work well in small medical devices. In the same way, we have been thinking about many features for this type of muscle. In the future, artificial muscles could give robots a more natural look in their facial expressions.

And is that the laboratory will now try to build muscle longer strings. A production that could be applied as explained mesh cover for firefighters’ uniforms. A fabric that automatically seal your pores when faced with a crisis situation.

Muscles are made of strings built of carbon nanotubes, a material extremely small that researchers will add all kinds of materials, such as water filters for experimental aircraft parts. Baughman explains the process:

What we did was twist the nanotubes, in a way very similar to what is done with wool or cotton fibers in thicker yarns. After filling the hollow space in the nanotubes with different materials, including paraffin, beeswax candles going on.

To make the muscles contract, the researchers heated briefly. Once heated, the wax expands. When the wax cools again, it shrinks, and nanotubes become narrower and longer. This process can shorten and lengthen again every 25 milliseconds. These rapid contractions means that the muscles are able to perform a lot of work.

A type of tissue that researchers hope to change and become a standard in the future. Laboratories hope that someday they can weave cloth requiring fiber kilometers. They are even trying to make muscles that react to chemicals instead of heat.
