Abstract Ionic conductive hydrogels have emerged as an excellent option for constructing dielectric layers of interfacial iontronic sensors. Among these, gradient ionic hydrogels, due to the intrinsic elastic modulus, can achieve a wide range pressure responses. However, fabrication with optimal mechanical and sensing properties remains challenge. In this study, it is discovered first that phytic acid (PA) interacts in remarkably distinct manners (i.e., plasticizing effects phase separation) different polymers polyacrylamide polyacrylic acid). This distinctive PA‐polymer interacting mechanism innovatively utilized construct modulus hydrogel through simple precursor solution infiltration approach. The hydrogel‐based flexible sensor not only achieves high sensitivity (9.00 kPa −1 , <15 kPa) broad (from ≈3.7 Pa 1.2 MPa) simultaneously, but also exhibits superior low performance. It successfully recognizes subtle acoustic waves airflow, well moderate speaking finger pressing magnitude plantar pressure. addition, demonstrates remarkable antibacterial biocompatibility. functional performance bioactivity exceptional potential wearable applications.

Abstract Traditional hydrogels often face issues like dehydration, excessive swelling, and poor adhesion, limiting their practical applications. This study presents a facile universal method to create elastomer‐encapsulated with improved water retention, non‐swelling, enhanced adhesion. n‐Butyl acrylate (BA) 2,2,3,4,4,4‐hexafluorobutyl methacrylate (HFBMA) are utilized as the “soft” “hard” monomers, respectively, in situ construct elastomer coatings on hydrogel surface through surface‐confined copolymerization. The resulting transparent, hydrophobic, adhesive coating is tightly bound surface, conferring upon it robust defense against dehydration swelling various media, strong adhesion diverse substrates both aerial submerged conditions. Furthermore, this encapsulation strategy also augments mechanical attributes of bulk hydrogel, including its tensile properties puncture resistance, applicable wide array types configurations. Additionally, applied conductive results flexible sensors high sensitivity, reversible resistance change, exceptional sensing stability, significantly durability air underwater environments. These suggest potential applications harsh environments, such acoustic detection sonar scanning camouflage for submarines.

Abstract Mechanical information is a medium for perceptual interaction and health monitoring of organisms or intelligent mechanical equipment, including force, vibration, sound, flow. Researchers are increasingly deploying recognition technologies (MIRT) that integrate acquisition, pre‐processing, processing functions expected to enable advanced applications. However, this also poses significant challenges acquisition performance efficiency. The novel exciting mechanosensory systems in nature have inspired us develop superior bionic (MIBRT) based on materials, structures, devices address these challenges. Herein, first strategies pre‐processing presented their importance high‐performance highlighted. Subsequently, design considerations sensors by mechanoreceptors described. Then, the concepts neuromorphic summarized order replicate biological nervous system. Additionally, ability MIBRT investigated recognize basic information. Furthermore, further potential applications robots, healthcare, virtual reality explored with view solve range complex tasks. Finally, future opportunities identified from multiple perspectives.

Abstract Auxetic metamaterials refer to materials and structures with extraordinary deformation, i.e., transverse expansion (contraction) under uniaxial tension (compression). In recent decades, a very wide range of innovative functional performance has been discovered stemming from this behavior. This desirable exhibition adaptivity, programmability, functionality provides great potential in soft intelligent systems. However, thus far, the mainstream research on auxetic focused subjective design, monotonic mechanical properties, passive tunability. review thorough overview classical properties applications, primary objective proposing new roadmap auxetics for advances interdisciplinary field. The fundamental works are categorized different configurations mechanisms. particular, integration shape morphing, actuation, sensing, multiphysical response, inverse design is reviewed detail. To accelerate development smart structural systems, applications generalized into robotics (outside body), human–machine interaction (surrounding healthcare devices (inside body). Finally, several significant topics emphasized theory, material choice, manufacturing technique, applications.

Abstract The development of highly stretchable self‐powered electronic skins with a broad detection range is urgently needed but remains great challenge. Herein, unprecedented stretchable, broad‐range‐response, supercapacitor‐type, one‐body, and are developed by assembling porous polyurethane/polypyrrole electrode, polyacrylic acid/polyacrylamide ionic gel electrolyte, polyurethane/MXene electrode. folded structure the electrodes significantly enhances stretchability, while modulus‐gradient multilayer device effectively broadens pressure range. combine dynamic/static sensing, ultrabroad (20 Pa–3.5 MPa), ultrahigh stretchability up to 387%, excellent compression stability (5000 cycles under 195 kPa), good stretching (500 200% tensile strain). They have capability monitoring human body motions, physiological signals, high pressures from motorcycle tires, as well tactile sensing robotic grippers. In addition, they can be applied for thermal management electromagnetic shielding devices. This work provides new strategy multifunctional wearable electronics sensors.
