New work out of Georgia Tech promises to lend a sense of permanence to shape-shifting 3D printing. The technology, commonly referred to as 4D printing by those in the know, aims to add another ...

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 ...

(Nanowerk Spotlight) Water contains tremendous untapped energy, but very little of it is being harnessed currently. On a large scale, dams harvest hydroelectric power, while tidal and wave energy ...

Using a new technique known as 4D printing, researchers can print out dynamic 3D structures capable of changing their shapes over time. Such 4D-printed items could one day be used in everything from ...

Researchers at the University of Wollongong, Australia have created a 3D printer-compatible hydrogel that is mechanically tough and able to repeatedly change shape in response to water temperature.

Now, 4D technology has been used to create a soft robot capable of analyzing the soil. Drawing inspiration from the seed structure of the South African geranium (Pelargonium appendiculatum), which ...
