Penn State researchers just created a hydrogel "skin" inspired by octopuses that can hide images and change shape on command, triggered by heat, liquids, or stretching. The clever part: digital instructions are printed directly into the material itself. This kind of programmable matter opens interesting doors for soft robotics and adaptive interfaces.

Scientists create smart synthetic skin that can hide images and change shape

Inspired by the shape-shifting skin of octopuses, Penn State researchers developed a smart hydrogel that can change appearance, texture, and shape on command. The material is programmed using a special printing technique that embeds digital instructions directly into the skin. Images and information can remain invisible until triggered by heat, liquids, or stretching.
