Abstract Electrochemical glucose biosensors are essential for diabetes management, and self‐powered systems present an eco‐friendly innovative alternative. Traditional face several limitations including limited sensitivity, enzyme instability, dependency on external power sources. Addressing these issues, the study develops a novel multifunctional nanofiber integrating biosensor detection motion sensor, utilizing triboelectric nanogenerator (TENG) system. Electrospun nanofibers, composed of graphene oxide (GO), porous (PG), foam (GF), polypyrrole (PPy), polycaprolactone (PCL), demonstrate enhanced electrical conductivity, efficiency, mechanical strength. Among these, dip‐coated nanofibers exhibited highest conductivity 4.9 × 10⁻⁵ S/cm, attributed to superior surface properties GO. PCL/PPy/GO achieved performance in cyclic voltammetry differential pulse due efficient electron transfer mechanisms GO PPy. Additionally, tests revealed peak voltages 63V with polyvinylidene fluoride containing oxidase enzyme. Core‐sheath also demonstrated significant resilience (∼0.9 N force, ∼350 s durability). These findings highlight as multifunctional, efficient, scalable solution, offering highly sensitive non‐invasive sweat analysis along robust energy harvesting environmentally friendly advanced management systems.

At present, using biomass materials to modify graphene oxide (GO) enhance the anticorrosion performance of coatings meets requirements future sustainable development. In order endow lignin/GO with self-healing function reduce maintenance costs and avoid accidents caused by material corrosion failure, this work utilized electrostatic interactions load zinc ions onto (Zn@LGO). Experimental results indicated that cured coating exhibited both photothermal conversion properties. When content Zn@LGO was 0.4 wt%, surface temperature rose 139.2 °C after 180 s near-infrared radiation. The left for 100 days in salt water, Z0.01Hz value VER-3 up 1.3 × 109 Ω cm2, which two orders magnitude higher than pure resin coating, fewer products were observed on metal surface. scratch test showed damaged soaked 3.5 wt% sodium chloride 72 h; charge transfer impedance 2.61 104 one coating. This mainly because during corrosion, hydroxide generated combination at cathode covered area hindering penetration corrosive medium. All all, research promoted application lignin, also provided a reference design composite
