Abstract Wavelength-tunable structural colors using stimuli-responsive materials, such as chiral liquid crystals (CLCs), have attracted increasing attention owing to their high functionality in various tunable photonic applications. Ideally, on-demand omnidirectional wavelength control is highly desirable from the perspective of wavelength-tuning freedom. However, despite numerous previous research efforts on CLC colors, only mono-directional tuning toward shorter wavelengths has been employed most studies date. In this study, we report ideally desired longer and with significantly improved tunability over a broadband range. By areal expanding contractive strain dielectric elastomer actuators (DEAs) crystal elastomers (CLCEs), simultaneous color-tuning was achieved.
