Stanford scientists created a flexible material that can rapidly change its surface patterns and colors. This innovation could lead to improved camouflage systems for humans and robots, as well as flexible displays.

Imagine having a material that can change color and texture like an octopus. Scientists at Stanford have made this possible with a new flexible material that can quickly shift its surface patterns and colors. This breakthrough could lead to improved camouflage systems for both humans and robots, as well as flexible displays that change color for wearable devices.

The team used a combination of electron-beam lithography and a water-responsive polymer film to create the shape-shifting material. When exposed to a focused beam of electrons, specific regions of the film become more or less absorbent. As the material takes in water, those regions swell differently, forming intricate patterns that only appear when the film is wet.

The researchers even created a tiny version of Yosemite's El Capitan using this technique. By carefully adjusting how much the material swells, they can also control how it reflects light, making it possible to switch between glossy and matte finishes.

Why It Matters

This innovation could lead to more advanced camouflage systems for Indian soldiers and robots, as well as flexible displays that change color for wearable devices like smartwatches or fitness trackers.
