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 ...

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 ...

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 ...

Historically, data center design was linear: Size the facility to meet demand forecasts and hope for the best. Power and ...

[Asia Economy Reporter Kim Bong-su] A domestic research team has developed a polymeric new material for 4D printing that can self-heal wounds and has shape memory capabilities. The Korea Research ...

(Nanowerk Spotlight) Smart materials that can change their properties like color or shape in response to external stimuli are highly desirable for advanced applications like soft robotics, adaptable ...

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 ...

A recent article published in Small Science introduces fully bioderived, four-dimensional (4D) printable shape memory polymers (SMPs) with linear tunability and remotely controlled actuation ...

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 ...
