Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications. [PDF]

open access: yesAdv Mater
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.
