Figure | Schematic illustration showing the design of soft robotic system with integrated information encoding, encryption, display, and execution functionalities. a, The intrinsic photoalignment capability of LCs is exploited to record phase holograms using a digital micromirror device (DMD)-based micro-lithography system, thereby encoding task-specific optical information directly into a solid-state LCN film. b, Leveraging the shape programmability and dopant-hosting ability of SF, the morphing SF layer, doped with upconversion nanoparticles (UCNPs), provides both three-dimensional architecture and near-infrared (NIR)-excitable fluorescence for optical encryption. c, Following predefined decryption scheme, illumination with circularly polarized light (CPL) reconstructs distinct holographic images from the LCN layer, which exhibit a one-to-one correspondence with the fluorescence colors of the SF layer. This correlation enables reliable information extraction and multidimensional optical display. d, The decoded holographic images thus act as optical command interfaces, allowing operators to interpret encoded instructions and execute tasks with precise guidance.
