Abstract With the onset of 5G era, wearable flexible electronic devices have developed rapidly and gradually entered daily life people. However, vast majority research focuses on integration functions performance improvement, while ignoring electromagnetic hazards caused by devices. Herein, 3D double conductive networks are constructed through a repetitive vacuum‐assisted dip‐coating technique to decorate 2D MXene 1D silver nanowires melamine foam. Benefiting from unique porous structure multi‐scale interconnected frame, resultant composite foam exhibited high electrical conductivity, low density, superb interference shielding (48.32 dB), Joule heating (up 90.8 °C under 0.8 V). Furthermore, single‐electrode triboelectric nanogenerator (TENG) with powerful energy harvesting capability is assembled combining an ultra‐thin Ecoflex film polyvinylidene fluoride film. Simultaneously, foam‐based TENG can also be considered reliable sensor for monitoring activity patterns in different parts human body. The versatility scalable manufacturing high‐performance foams will provide new design ideas development next‐generation

Abstract Smart flooring embedded with TENG technology enhances safety and security in dream homes by generating energy through movement, providing real‐time alerts monitoring capabilities. Research on smart is limited, particularly concerning its washability, which remains a significant drawback. To tackle this challenge, an innovative solution developed that not only washable but also flexible durable, combining barium titanate (BT) graphite fluorinated polymer (FG) within Ecoflex (EC) matrix, utilizing sandwich‐style single‐electrode (SWSE‐TENG) configuration. This design exhibits remarkable triboelectric performance, achieving open‐circuit potential of 1000 V short‐circuit current 25 µA when tapped nitrile‐glove‐clad hand. Extensive testing under various conditions such as humidity, water immersion, frequent washing demonstrates outstanding stability resilience. The SWSE‐TENG shows promising applications safety, security, athletic environments. Prior to this, EC‐BT‐FG composites varying BT FG concentrations using facile casting technique are fabricated, systematically analyzing their structural, crystalline, electrical properties. Notably, the 5 wt% EC composite (EC‐5‐5) superior making it optimal choice for solution.

With the rapid advancement of electronic technology, demand for wearable and portable devices has significantly increased. MXene-based multifunctional textiles have attracted extensive attention from researchers due to their unique various functionalities, while poor oxidation structure stability limit applications. In this study, a novel MXene/tannic acid-modified cellulose nanofibers (TACNF)-based textile was prepared by screen-printing post treatment. The abundant phenolic hydroxyl groups in TA effectively protect MXene nanosheets oxidation. subsequent ZnCl2 cross-linking treatment leads metal coordination between Zn ions molecules, which further improves composite coating endows functional with enhanced antimicrobial activity against Escherichia coli Staphylococcus aureus. rationally designed electrically conductive demonstrates decent sensing ability toward tiny large human motions, its exceptional photo-/electro-thermal conversion also enables promising potential applications thermal therapy heat sterilization. This study provides new insights design fabrication smart healthcare textiles.

Abstract With advancements in radar detection technology, electromagnetic stealth has garnered significant attention military applications. Traditional absorbers typically focus on tuning parameters; however, they are often limited by material constraints, resulting effective absorption only within narrow frequency bands. This work presents a novel prism‐honeycomb nested microwave absorbing structure, inspired the scattering phenomenon of light waves prism, which utilizes an enhanced effect. The varying impedances (EMWs) different media lead to transmission and reflection that adhere Snell's law at interfaces. To optimize effect, inner prism is filled with high transmittance material, while outer honeycomb structure incorporates dielectric loss. Consequently, experience attenuation unit. Despite thickness 7 mm, this achieves over 90% EMW across broad range 1–18 GHz. Additionally, exhibits excellent mechanical load‐bearing capacity. nesting further enhances support points, compressive strength 16.4 MPa. innovative design not facilitates full‐band but also provides capabilities, offering valuable insights for applications camouflage.
