Abstract Smart hydrogels with multi‐fluorescent properties hold great promise for information encryption. However, conventional fluorescent often lack adequate mechanical and multiple responsiveness, limiting their range of applications. In this study, a multifunctional hydrogel featuring an interpenetrating polymer network (IPN) composed poly(vinyl alcohol) (PVA) poly(acrylic amide‐co‐2‐acrylamido‐2‐methylpropane sulfonic acid) P(AM/AMPS) chemical cross‐linking networks is designed. Through the coordination lanthanide ions (Eu 3+ , Tb ) glycine, achieves exceptional stretchability (over 900%) adjustable photoluminescence properties. Due to acid groups on 2‐acrylamide‐2‐methylpropanesulfonic (AMPS), which support various noncovalent interactions, PVA‐P(AM/AMPS)‐Gly‐Ln displays strong reversible adhesive diverse substrates. Ultimately, assembled into multifunctional, flexible sensor, boasting satisfactory sensitivity (GF = 5.3), rapid response rate (100 ms), outstanding characteristics, highlighting its potential applications in human motion detection

Leveraging the rich stimuli-response of polymers represents a promising direction towards optical communication/encryption. Sign language, which relies on specific geometric change for secured communication, has been widely used same purpose since ancient time. We report strategy that combines both in validated manner with hydrogel not only carries encrypted information but also hidden behavior to morph geometrically. In particular, shape morphing is programmable by controlling oriented state polymer chain thermo-responsive network. Whether positive (bending) or negative (flattening) cannot be predicted when polymerization methods are informed, revealing manner. Through deciphering coupling elastic stresses and thermo-induced deswelling stress, can perform designed diversified 4D evolution 3D geometries time as fourth dimension. Consequently, corresponding gated based these features, thereby decrypting correct permutation information. Our approach utilizes verification offers enhancing security communication ways quite different from existing strategies. Stimuli responsive hydrogels always complex required. Here, authors use
