Reasearcher: Artificial muscles was more stronger

A researcher of NanoTech Institute, University of Texas, Carter Haines  is currently combining the polymer fishing line with sewing thread. Result is believed to be formed an artificial muscles that have extraordinary abilities.
DIY muscle: Using just ordinary fishing line and sewing thread, a team of international scientists have found a way to turn them into artificial muscle 100 times stronger than our own. They come in a variety of widths (pictured) to suit different purposes from heavy lifting to enabling delicate movements. (Picture from: http://www.thisismoney.co.uk/)
"When compared with natural muscle, this artificial muscle's has strength hundredfold," he said, as quoted by VOA News, on Friday, February 21, 2014. Haines reveal the artificial muscles that can lift loads up to 7,25 kg. This means that the muscle can be used for human robots, prosthetic limbs and external skeletons for individuals with paralyzed muscle.

"We'll see if, rather than using, for example artificial limbs, we can replace it with something more fitting to the feet or hands that have lost their function," he said further.

According to the report, the scientists said braided sewing thread with a diameter less than a strand of human hair can also be used for applications that do not need power. For example, a synthetic muscle can move the mechanical robots that perform minor surgery, said Haines.
The muscles are powered by temperature changes that can be produced electrically. When the polymer fibre coils like a heavily twisted rubber band, it produces a muscle that dramatically contracts along its length when heated and returns to its initial length when cooled (pictured).

When heated, rotating and muscle contraction to generate power, and when cooled, the muscles become relaxed. Artificial organs that can be powered through a temperature difference or simple battery.
Strong: The artificial muscles can lift 100 times the weight and generate 100 times the mechanical power compared to a human muscle of the same length and weight. Their strength when used in parallel like human muscles are demonstrated here in the lab. (Picture from: http://www.thisismoney.co.uk/)
When stitched on fabric, yarn Haines said it could open the pores so that the clothes when hot and cold air in otherwise close the pores of fabric when cold.

The muscles that are easy to make, according to Haines, because it uses materials that can be purchased in stores. School children who learn the technology that uses synthetic muscles for school science projects them .. *** [EKA | FROM VARIOUS SOURCES | VOA NEWS]
