Precise optical and thermal regulatory systems are found in nature, specifically in the microstructures on organisms’ surfaces. In fact, the interaction between light and matter through these microstructures is of great significance to the evolution and survival of organisms. Furthermore, the optical regulation by these biological microstructures is engineered owing to natural selection. Herein, the role that microstructures play in enhancing optical performance or creating new optical properties in nature is summarized, with a focus on the regulation mechanisms of the solar and infrared spectra emanating from the microstructures and their role in the field of thermal radiation. The causes of the unique optical phenomena are discussed, focusing on prevailing characteristics such as high absorption, high transmission, adjustable reflection, adjustable absorption, and dynamic infrared radiative design. On this basis, the comprehensive control performance of light and heat integrated by this bioinspired microstructure is introduced in detail and a solution strategy for the development of low‐energy, environmentally friendly, intelligent thermal control instruments is discussed. In order to develop such an instrument, a microstructural design foundation is provided.

“…With an approach to fabricate wearable camouflage products, magnetically responsive stretchable/squeezable poly(dimethylsiloxane) (PDMS) fibers have been prepared. The fibers contain carbon‐encapsulated Fe 3 O 4 @C super‐paramagnetic colloidal nanocrystal clusters, which change color from brown to yellowish green in the presence of an external magnetic field . The Fe 3 O 4 @C nanoclusters are embedded in ethylene glycol droplets, so they can freely move.…”

Stimuli-responsive colors are a unique characteristic of certain animals, evolved as either a method to hide from enemies and prey or to communicate their presence to rivals or mates. From a material science perspective, the solutions developed by Mother Nature to achieve these effects are a source of inspiration to scientists for decades. Here, an updated overview of the literature on bioinspired stimuli-responsive color-changing systems is provided. Starting from natural systems, which are the source of inspiration, a classification of the different solutions proposed is given, based on the stimuli used to trigger the color-changing effect.

“…Different from aqueous systems, solvation forces in nonaqueous solutions, such as alkanol solutions, become major repulsive forces . Notably, to ensure that the ferromagnetic particles are sufficiently dispersed, surface modification of ferromagnetic particles with silica or carbon shell is of necessity and carried out first. The alkanol solutions of modified ferromagnetic particles are then mixed with nonaqueous prepolymer as separate liquid droplets using mechanical stirring.…”
