Abstract Biological structures provide inspiration for developing advanced materials from sustainable resources, enabling passive structural morphing. Despite an increasing interest parsimony‐oriented innovation, shape‐changing based on renewable resources remain underexplored. In this work, the architecture of a single plant fiber cell wall (S 2 , instance) is simplified to design novel concepts 4D printed tubular moisture‐driven actuators, using hygromorphic properties continuous flax (cFF) reinforced materials. This new class bioinspired active referred as metabiocomposites. Before design, are produced with customized rotary 3D printer, qualified, and tested sorption behavior. A parametric experimental, analytical, FEA analysis highlights programmability material through effects mesostructural parameters (printing inclination α) geometric factors (operational length L, inner diameter D, thickness h) actuation authority. The overall performance trade‐off between rotation torque, energy density comparable that source inspiration: natural fibers wall. potential applications illustrated proof concept meteosensitive rotative structure transmits motion external device, such solar tracker.

Abstract Stimuli‐responsive actuators are candidates for the development of soft robots due to their shape deformation and environmental adaptation capabilities. Adaptation stimuli not only enables complex reprogramming but also benefits recovery mechanical injuries actuators. Nevertheless, reports on that integrate shape‐reprogramming injury‐healing functions into a monolithic actuating material through facile fabrication strategies remain scarce. Herein, stimuli‐responsive healable actuator is developed via layer‐by‐layer casting two materials with complementary properties. Upon specific stimulation, these reorganize structural network at nano‐ microscales heal. The resulting exhibits robust photo‐responsive strength asymmetric volumetric responses layers. Importantly, whole can be healed aid sequential heating‐humidifying–drying treatment, achieving excellent healing efficiency in both (72%) (95%). Moreover, initial actuation modes restored diversified humidifying or heating‐assisted welding procedures, respectively. This work demonstrates strategy construct reprogrammable abilities stimulated by provides platform developing adaptable changing environment.

The chapter explores the integration of defence-grade materials into construction to enhance infrastructure resilience. Advanced like carbon fibre, Kevlar, graphene composites, and multifunctional geopolymers offer high strength, durability, self-healing properties. Bio-inspired innovations, including mechanoluminescent, hydrophobic, energy-autonomous materials, have successfully transitioned civilian applications, improving seismic resilience, structural health monitoring, environmental protection. Despite cost scalability challenges, ongoing research in 4D printing, nanotechnology, systems is driving broader implementation. Increased investment advanced underscores their crucial role developing sustainable, adaptive, high-performance urban infrastructure.
