“…As the new generation of artificially designed optical material, photonic crystals (PCs) have unique periodic structures and optical characteristics—photonic bandgap (PBG)—which can alter the wavelength of reflected light when the stimuli such as pH, temperature, and pressure change the structural color of the PCs [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. Therefore, PCs have been playing an important role in environmental protection, biomimetic, and energy materials, especially in the field of biosensing [ 12 , 13 , 14 , 15 , 16 , 17 ]. However, the rigidity of the PCs reduces their stability and limits their further application in wearable sensors.…”

Flexible wearable materials have frequently been used in drug delivery, healthcare monitoring, and wearable sensors for decades. As a novel type of artificially designed functional material, photonic crystals (PCs) are sensitive to the changes in the external environment and stimuli signals. However, the rigidity of the PCs limits their application in the field of biometric and optical sensors. This study selects silk fibroin (SF) and poly-N-isopropylacrylamide (PNIPAM) as principal components to prepare the hydrogel with the physical crosslinking agent lithium silicate (LMSH) and is then integrated with PCs to obtain the SF-PNIPAM dual-crosslinked nanocomposite for temperature and strain sensing. The structural colors of the PCs change from blue to orange-red by the variation in temperature or strain. The visual temperature-sensing and adhesion properties enable the SF-PNIPAM dual-crosslinked nanocomposite to be directly attached to the skin in order to monitor the real-time dynamic of human temperature. Based on its excellent optical properties and biocompatibility, the SF-PNIPAM dual-crosslinked nanocomposite can be applied to the field of visual biosensing, wearable display devices, and wound dressing materials.

“…With chemically or physically crosslinked three-dimensional (3D) network structures, polymer hydrogels possess the ability to absorb large amounts of water and resist dissolution. [1][2][3] The excellent biocompatibility, porous structure, tunable stiffness, and biological tissue-like elasticity of polymer hydrogels impart widespread use as biomaterials in the elds of tissue engineering, [4][5][6] gene and drug delivery systems, [7][8][9] cell cultures, [10][11][12] superabsorbents, [13][14][15][16] biosensors, [17][18][19][20] articial e-skins, [21][22][23] wound healing, [24][25][26] etc. However, conventional chemically crosslinked hydrogels are always brittle and exhibit poor mechanical performance due to the absence of an energy dissipation mechanism, limiting their widespread applications.…”
