Synthetic materials are widely used across science, engineering, and industry, but most are designed to perform only a narrow range of tasks. A ...

The octopus-inspired material could lead to better camouflage technology for the military and beyond.

The hydrogel behaves like a programmable canvas. Rather than using traditional pigments, researchers embedded data directly ...

New fabrication method produces hydrogel-based smart synthetic skin with adjustable optical, mechanical, and surface ...

US researchers have developed a synthetic “smart skin” that can change its appearance, texture, and shape when exposed to heat, liquids, or mechanical stress. The team used a novel 4D-printing method ...

US researchers have developed a 4D-printing method for hydrogel ‘smart synthetic skin’ that hides and reveals images on demand, with potential uses in information encryption and adaptive camouflage.
