The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Colorimetric description of thermochromic printing inks
The dynamic colour of three commercial reversible thermochromic inks were studied. Thermochromic print-ing inks change their colour according to a change in temperature. The two types of thermochromic inks are based on leuco dyes and liquid crystals. The thermochromic effect achieved by liquid crystals is quite different from the effect achieved with ...

A versatile approach is presented for fabricating smart multifunctional textiles by integrating thermo‐fluorescent carbon dot/polymer nanocomposite coatings with 3D‐printed interlocked architectures. The fabrics exhibit temperature‐responsive fluorescence, durable hydrophobicity, strong antibacterial and antioxidant activity, and enhanced UV protection.

How to Visually Represent the Colour Theory of Thermochromic Inks
Colour theories have been established in order to allow artists and designers to understand the relationship between colours, and to determine how a chosen colour will react or interact with another. Smart colours - such as leuco dye-based thermochromic inks - have entered into the textile and fashion design world, bringing with them new challenges ...

ON TEXTILE PRINTING WITH THERMOCHROMIC INKS
What are thermochromic inks? They are colouring agents characterised by their ability to, when printed on textiles, change colour in response to temperature fluctuations. Below their activation temperature they are coloured, and above their activation temperature they are clear or have a light hue.

On textile printing with thermochromic inks
This thesis describes an exploration of the principles of applying leuco dye-based inks to textile design practice. The main motivation has been to explore the design properties and potentials of leuco dye-based thermochromic inks when printed on textiles in order to obtain an understanding and facilitate the design of dynamic surface patterns.
