4D Encryption System: Hydrophilic–Hydrophobic Polyurethane Actuators with Smart Color Switching for High‐Capacity Data Storage

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

Abstract Natural communication methods have influenced the creation of sophisticated artificial materials capable coherent and abundant responses to stimuli, a crucial necessity for developing applications such as dynamic encryption systems high‐density information storage. However, existing storage are limited by predictable, single‐stimulus lack capacity dynamic, continuous, programmable changes. To address this gap, bioinspired multicolor fluorescent polyurethane actuator is developed that combines color shape adaptability within single material platform. This smart mimics turgor‐driven movements Oxalis corniculata through hydrophilic/hydrophobic network enables water diffusion, hydrogen bonding, bond exchange. It responds multiple including temperature, pH, excitation wavelength, exhibiting reversible multi‐state deformations fluorescence across red, green, blue, even white light. The deformation behavior supported finite element simulations, ensuring precise control predictability. Additionally, tunable trichromatic underpins 3D 4D encoding system, demonstrating increased security. employment micro‐processing technology in fabrication micro‐hidden optical chips has been demonstrated, thus paving way underwater technologies adaptive materials.
