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 ...

During the early stages of life, organs do not just appear in their final form. They take shape through a process of controlled bending, twisting, and folding. These changes help cells organize into ...

Computer animation may be a lot better than it used to be, but it’s been around for quite a while. This is an example of one of the older bits, dating way back to 1965, and it features some 4D shapes.

Combining materials with different swelling ratios creates structures that transform into tubes when exposed to water. (Courtesy: Yu Bin Lee) Materials that controllably change shape over time – often ...

Move on over 3D printing, because 4D printing is taking the spotlight. (WATCH FULL VIDEO BELOW, transformation near end of clip) Scientists at Harvard University created a new 4D printing method— ...

Drawing inspiration from how plants change shape in response to environmental stimuli, Harvard scientists from the Wyss Institute and John A. Paulson School of Engineering and Applied Sciences have ...

Three dimensional printing is about to become so passé – welcome to the world of 4D printing. A team of scientists has created a technique for printing objects that can change their shape over time ...

New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a ...
