Abstract Stimuli‐responsive structural‐color materials have received widespread attention in information encryption due to the significant color changes under different stimuli. However, trade‐off between capacity of input, security level, cost, and large‐area manufacturing greatly limits application structural colors encryption. Herein, dynamic high‐capacity high‐resolution are achieved by implementing printed total internal reflection (TIR) computer‐aided image recognition. The TIR microstructures prepared with relative humidity (RH) responsive polymer, which form a heterogeneous wettability system, can exhibit vibrant variation humidity. As implemented RH is changed, will expand or shrink precisely, enabling full‐color modulation across visible light range. With change, each pixel be specifically encoded, allowing for this encrypt within same pattern at RHs. Furthermore, This study precisely integrates tremendous pixels easily prepare various encrypted patterns, guarantee input low‐cost way. Moreover, through computer programming algorithm reading, patterns decoded decrypted real‐time, thus offering great potential further encryption, anti‐counterfeiting, multiplexing encoding, data storage.

Stimuli-responsive structurally-colored materials have been extensively developed for decades based on conventional strategies by manipulating periods and refractive indices of the system. Herein, a controlled incoherent scattering strategy is demonstrated fabricating stimuli-responsive photonic glass featured high contrast scalable produce. The in systems responsive light absorbers wetting, leading to conversion between whitened state dominated structural resonance. Wetting system reduces significantly reveal color glass, while engineered can change absorption with stimuli-response shift shield against scattering. Responsive colors are presented, realizing wetting-, humidity- temperature-dependent sensors patterns. Given that such incoherent-scattering-controlled response shows higher than shifting reflectance bands systems, this work may inspire effective invisible patterning capability anti-counterfeiting sensors.
