“…When the alignment was vertical, the wavelength of Bragg reflection shifted to blue, and when it was planar, the wavelength shifted to red [ 125 ]. Mateusz Mrukiewicz et al reported that by simultaneously irradiating the structure with ultraviolet light and applying an electric field, the structure color can be adjusted [ 126 ]. With newly designed rod-shaped, chiral, and curved azo photosensitive materials, doping cholesterols with oblique helical structures is characterized by a very low thermal back cis–trans isomerization rate.…”

Creatures in nature make extensive use of structural color adaptive camouflage to survive. Cholesteric liquid crystals, with nanostructures similar to those of natural organisms, can be combined with actuators to produce bright structural colors in response to a wide range of stimuli. Structural colors modulated by nano-helical structures can continuously and selectively reflect specific wavelengths of light, breaking the limit of colors recognizable by the human eye. In this review, the current state of research on cholesteric liquid crystal photonic actuators and their technological applications is presented. First, the basic concepts of cholesteric liquid crystals and their nanostructural modulation are outlined. Then, the cholesteric liquid crystal photonic actuators responding to different stimuli (mechanical, thermal, electrical, light, humidity, magnetic, pneumatic) are presented. This review describes the practical applications of cholesteric liquid crystal photonic actuators and summarizes the prospects for the development of these advanced structures as well as the challenges and their promising applications.
