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 ...

Researchers have created software and hardware for a 4D printer with applications in the biomedical field. In addition to 3D printing, this machine allows for controlling extra functions: programming ...

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 ...

(Nanowerk Spotlight) The next generation of robots may not look anything like the rigid, mechanical machines we’re used to. Instead, imagine a robot that moves more like an octopus or a human hand, ...

The 4D material changes shape in response to water. The grey side of the material in the image absorbs water faster than the blue side, causing it to bend into a "C" shape. Disclaimer: AAAS and ...

Researchers have developed a way to fabricate a new type of wing that can change its shape in flight for unmanned aerial vehicles (UAVs) cheaply and efficiently using a novel 4D-printing process, they ...
