Shape-memory metals, which can revert from one shape to a different one simply by being warmed or otherwise triggered, have been useful in a variety of applications, as actuators that can control the ...

Scientists at Tomsk Polytechnic University (TPU), in collaboration with colleagues from the Institute of Strength Physics and Materials Science of the Siberian Branch of the Russian Academy of ...

With 4D printing, the objects can change shape or properties using external stimuli such as temperature, light, pH, magnetic field, electricity, and moisture. Additionally, the changes in shape or ...

How a special nitinol compound and 3D printing was used to create the shape-shifting antenna. An overview of materials and heating problems they encountered, and how they overcame them. The test ...

Engineers have created shape-memory materials made of ceramic rather than of traditional metal. The development opens a new range of applications, especially for actuators in high-temperature settings ...
