Artificial muscles show more flex

Artificial muscles made significant gains when a literal twist in the development approach uncovered the tensile—or stretchy—abilities of polymer fibers once they were twisted and coiled into a spring-like geometry. In ...

3-D printed structures that 'remember' their shapes

Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that "remember" their original shapes. Even after being stretched, twisted, and bent at extreme ...

4-D technology allows self-folding of complex objects

Using components made from smart shape-memory materials with slightly different responses to heat, researchers have demonstrated a four-dimensional printing technology that allowed creation of complex self-folding structures.

New self-stretching material developed

Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation.

'Smart' medical material aims to unfurl at 98.6 degrees

(Phys.org) —Mechanical Engineering Professor Lih-Sheng (Tom) Turng has a simple office demonstration of how shape-memory polymers work. He takes the material, which is formed into a compact flower bud, drops the bud in ...

Researchers develop 4D printing technology for composite materials

(Phys.org) —Researchers at the University of Colorado Boulder have successfully added a fourth dimension to their printing technology, opening up exciting possibilities for the creation and use of adaptive, composite materials ...

Research that holds water

(Phys.org) —It's squishy, synthetic, flexible, mostly water and almost as tough as rubber. No, it's not "flubber"—it's a hydrogel, and now scientists at The University of Akron are exploring new biomedical uses for this ...
