  • Thermal and photothermal responsive.
  • Light responsive.
  • Highly stretchable.

Market Summary
The color-changing, chameleon-inspired, “smart skin” material in this disclosure is a type of smart hydrogel. The market for smart hydrogels was valued at $13.2 million in 2013 and was expected to reach $220 million by 2019 (BCC Research AVM023E). Furthermore, this invention, strain-accommodating smart skin (SASS), is made of nanoparticles and nanoclay. The global nanocomposites market is expected to reach $7.3 billion by 2022 from $2 billion in 2017 at a CAGR of 29.5% from 2017-2022 (NAN021H). SASS can potentially be used for military, consumer, and industrial applications.

Technical Summary
Researchers have developed a novel flexible smart skin which changes its color in response to heat and sunlight. The researchers designed a strain-accommodating smart skin (SASS) which was composed of two types of hydrogels. The responsive photonic crystal (PC) layer is composed of monodispersed Fe(3)O(4)@SiO(2) particles organized systematically and confined within a cross-linked poly(N-isopropylacrylamide) (pNIPAM) polymer). Finally, the robust supporting layer was composed nanoclay (Laponite XLG) doped tetra-polyethylene glycol (PEG).
