Scientist have recently discovered a new exotic material that somehow gets thicker when stretched
This new exotic material is call liquid crystal elastomer.
It’s the same liquid crystal material used to make flat screen monitors and TV displays.
“This behavior of increasing in thickness as a material is stretched is known as ‘auxetic’ behavior. Until now, manmade auxetics require a material prepared with specific structures allowing the auxetic response." Dr. Devesh Mistry from Leeds’ School of Physics and Astronomy
"Our material does not require such structures as the behavior is inherent to the material, and is a result of molecular restructuring inside the material.” Dr. Devesh Mistry from Leeds’ School of Physics and Astronomy
