Ein US-Team entwickelt ein neues Metamaterial, das sich ohne Motoren selbst bewegt & Form ändert – fast wie ein Roboter! 
Inspiriert von Origami, reagiert es auf Magnetfelder und könnte Gebäudeheizung & -kühlung revolutionieren

A bent blade is equivalent to a beam that would be placed along the line of the crease at the intersection of two planes. If you look carefully, each of the strips emulates the lines of the #metamaterial design on one level. Strips are misaligned on the photo but I believe that when I actually model this concept in the computer it will be much more clear how they should connect.

“Surprisingly, about 40 minutes into the experiment, the damage reversed course. One end of the crack fused back together as if it was retracing its steps, leaving no trace of the former injury. Over time, the crack regrew along a different direction.
Hattar called it an “unprecedented insight.”
Boyce, who was aware of the theory, shared his findings with Demkowicz.
“I was very glad to hear it, of course,” Demkowicz said. The professor then recreated the experiment on a computer model, substantiating that the phenomenon witnessed at #Sandia was the same one he had theorized years earlier.
Their work was supported by the #DepartmentOfEnergy’s Office of Science, Basic Energy Sciences; the National Nuclear Security Administration and the National Science Foundation.”
