Advanced epidermal electronic devices, capable of real-time monitoring physical, physiological, and biochemical signals administering appropriate therapeutics, are revolutionizing personalized healthcare technology. However, conventional portable devices predominantly constructed from impermeable rigid materials, which thus leads to the mechanical disparities between human tissues, resulting in skin irritation, tissue damage, compromised signal-to-noise ratio (SNR), limited operational lifespans. To address these limitations, a new generation wearable on-skin electronics built on stretchable porous substrates has emerged. These offer significant advantages including breathability, conformability, biocompatibility, robustness, providing solutions for aforementioned challenges. given their diverse nature varying application scenarios, careful selection engineering suitable is paramount when developing high-performance tailored specific applications.

A closed-loop pathway of "efficient actuation-synchronous sensing-multimodal feedback" is crucial for actuators to adapt complex scenarios and human-environment interactions. Strategies reconcile mechanics-guaranteed adaptive actuation with multimodal responses perceptivity remain challenging. Through a continuous electrospinning strategy construct reinforced fiber-interlocked interface, bilayer fiber membrane (TCTR) actuator composed highly aligned hierarchical structures developed obtain efficient photothermal performance (22.9 °C min-1), excellent mechanical toughness (17.9 MJ m-3), intuitive color changes (dark purple red bright pale yellow lightness variation 68). This humidity-dominated photothermal-assisted-responsive demonstrates superior response (0.67 cm-1 s-1) bending curvature (7.37 cm-1) electro-visual cooperative perceptivity. Integrated the actuation-triggered triboelectric self-powered sensing synchronous thermochromic effect, TCTR can be differentially programmed perceive material types object temperature (with sensitivity 99.5%), visualize writing paths. By optimizing alignment assembly pattern, utility as filter material, smart mask, electronic textile, which sense air contamination degrees, environmental temperature, respiratory status, well achieve thermal management/alarming. work proposes materials mechano-electrical-optical cooperation inspires facile interactive multiscenario adaptivity.

Elastic electromagnetic fibers are promising building blocks for next-generation flexible electronics. However, fabrication of elastic is still difficult and usually requires organic solvents or high temperatures, restricting their widespread applications. Furthermore, the continuous production has not been realized previously. In this study, we propose an ionic chelation strategy to continuously produce with a magnetic liquid metal (MLM) as core polyurethane sheath in water at room temperature. Sodium alginate (SA) introduced rapidly chelate calcium ions (Ca2+) coagulation bath support spinning waterborne (WPU) sheath. Meanwhile, WPU-encapsulated MLM microparticles efficiently suppress fluid instability extrusion core. The resultant fiber exhibits excellent mechanical performances (tensile strength toughness up 32 MPa 124 MJ/m3, respectively), conductive stability large deformations (high conductivity 7.6 × 104 S/m 580% strain), magnetoactive properties. applications have demonstrated by conductance-stable wires, sensors, actuation, interference shielding. This work offers water-based molecular principle efficient green multifunctional will inspire series

Abstract Realizing stretchable conductive fibers with a trade‐off between stretchability and conductivity is important for wearables. Fibrous triboelectric nanogenerators (FTENGs) represent promising device wearable power sources self‐powered sensors. However, the relationship outputs of FTENG remains unfathomed. Herein, simple strategy fabricating binary rigid‐soft components dynamic compensation capability reported. Wet‐spun thermoplastic polyurethane (TPU)/silver flakes (AgFKs) (TA) composite fiber fabricated coated by water‐borne (WPU) thin layer, bridging subsequent liquid metal (LM) coating to obtain TPU/AgFKs/WPU/LM (TAWL) fibers. The TAWL shows outstanding elongation (~600% strain), electrical ~2 Ω cm −1 (~3125 S ), reversible resistance response within 70% tensile strain.
