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 ...

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 ...

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 ...

(Nanowerk News) 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 ...

Where standard 3D printing uses a digital blueprint to manufacture an object out of materials like plastic or resin, 3D bioprinting manufactures biological parts and tissues out of living cells, or ...

Researchers at University of Galway have developed a way of bioprinting tissues that change shape as a result of ...

Although 4D printing is considered very promising for various biomedical applications – such as tissue scaffolds, neural scaffolds, grafts and stents, cardiac patches and valves, even bionic ...

Enter 4D materials, which are like 3D materials, but they change shape when they are exposed to specific environmental cues, such as light or water. These materials have been eyed by biomedical ...
