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 ...

Shape memory polymers (SMPs) are a remarkable class of stimuli‐responsive materials capable of undergoing substantial deformation and subsequently recovering their original shape when exposed to ...

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 ...

Laser powder bed fusion, a 3D-printing technique, offers potential in the manufacturing industry, particularly when fabricating nickel-titanium shape memory alloys with complex geometries. Although ...

In a recent review published in Micromachines, researchers from Spain and Portugal highlighted the synergistic combination of shape-memory polymers (SMP) with carbon nanotubes (CNT) to enhance ...

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 ...
