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.

4D Toys also works on iOS, Windows; was borne from upcoming puzzle game Miegakure. ... "It's just 4D shapes, as if you were a very young kid again and given a box of wooden toys.

Shape-Shifting Biomaterials for Tissue Regeneration In contrast to traditional tissue engineering materials, 4D printed materials can adapt to the constantly changing needs of the living body. Article ...

Italian researchers have created a novel 4D-printed biodegradable 'seed robot' that changes shape in response to changes in humidity and can navigate through the soil. The device has great ...

This capacity is known as the shape memory effect (SME), and it may occur in shape memory alloys (SMAs) and polymers (SMPs), but it is also feasible in shape memory hybrids (SMHs). Four-dimensional ...

A recent study published in Advanced Materials introduced a 4D printing method to create tubular moisture-responsive actuators called meta biocomposites. These structures use continuous flax fiber ...

New 4D bioprinting lets tissues change shape and grow stronger, bringing science closer to real, working lab-grown organs. (CREDIT: Adobe Stock) During the early stages of life, organs do not just ...
