MIT scientists have created material that can change shape and mimic a human face. This development can be used to quickly develop artificial muscles in the future.

A researcher at the Massachusetts Institute of Technology (MIT) Wim van Ries developed a method for turning a thin flat sheet into more complex forms - for example, into a human face. The scientist said that usually the surface cannot stretch, contract or tear, which creates a problem when researchers want to deform flat surfaces.

“My goal was to develop a technology that can help transform materials into complex, three-dimensional shapes using a simple method. But how to “program” the material so that it does it? ”, Rhys noted.

According to  hightech.fm, to solve this problem, Van Riesz and his colleagues decided to use a mesh lattice structure. They made it from a rubber material that expands with increasing temperature. The gaps in the grate make it easier to adapt the material to large changes in its surface area. The MIT team created a virtual face map, and then used the algorithm to convert to the correct drawing.

“This development can be used in the future to create artificial muscles, as the material can be brought into arbitrary shape,” the researchers noted.
