With the nano meter technology, it is not impossible to make a very stretchy material. Materials have been found with the use of certain types of rubber and carbon coating with nano meter scale. Super elastic material when it is made with the intended use of super elastic sensor. But when the super elastic material that is truncated, it is definitely the tool can not be reused. The invention allows for the production of super elastic and can heal themselves when cut. The researchers found the idea of human muscle to be stretched and can heal themselves after suffering an injury. When you pull a muscle a little force, perhaps you will feel extreme pain for a while. But the human body can heal any damage incurred as a result of this forced stretching muscles.
Now researchers makes it possible to replicate using electrically-responsive polymer. These polymers are used to make artificial muscle for robotic haptic systems and experimental. So when there are robots that use of these polymers in the cable and the other part, is expected when punctured or cut, the robot can heal themselves and can return to work as it should.
This is the first time the use of electrically responsive polymer with super elastic properties and can be self-healing, so it can be used as artificial muscles more resilient. Thanks to the super-elastic properties of the polymer used, a sheet of electrically responsive polymer with a length of 2.5 centimeters can be stretched up to 2.5 meters long. It’s fantastic not result ?! The researchers then tried to stab the polymer. When the polymer was stabbed, miraculously the polymer may recover. Even the electrically responsive polymer is able to heal themselves well in room temperature conditions.
Actually, the concept of a material that can heal itself is not a concept that was first thought. Other materials that can heal themselves has been discovered by researchers from the University of Illinois where they use certain plastic composites that repair themselves after a botched. However, research conducted by Stanford University included in the category of the more remarkable, because it combines the properties of super-stretchy and can heal themselves. This is a useful thing for the manufacture of electronic components and robot. Artificial muscles will contract when an electric field is passed through it, similar to the workings of biological muscles.
Self-healing polymer others will only heal themselves under certain conditions. They are cured by weak hydrogen bonds that are sensitive to moisture in the air. Instead, the material created by Stanford researchers could be placed in the open air and does not require special conditions to be able to heal themselves. While other designs have to be heated or compressed to trigger the self healing reaction. Stanford elastomer cures at room temperature without the need for any additional material. And after curing himself, electrical and mechanical properties will be as it was before the material is cut off.
Actually, elastic properties obtained from this material is an unexpected bonus. Researchers only intending to make elastomer that can heal more easily. Apparently when stretched to extremes, bonding in the polymer molecular scale will be quickly disconnected and re-established quickly, allowing the material to recover after being drawn to extremes. When tested in the lab, it turns this polymer can be drawn up to 10,000 percent. It is very elastic! Even the mechanical equipment-testing in the laboratory is not strong enough to pull it further.
