Abstract The development of safety alarm systems and sustainable power generators that can sustain extreme temperature environments contact with fire be lifesaving, but challenging at the same time. Here, a biomaterial (chitosan‐phytic acid) coated non‐flammable cotton fabric‐based triboelectric nanogenerator (TENG) is developed used as self‐powered system in situations. A single‐electrode mode‐based flame‐retardant TENG (FR‐TENG) fabricated using an aluminum electrode, chitosan, phytic acid‐coated fabric layer‐by‐layer (LBL) self‐assembly method active material. Structural, morphological, thermal characterization performed to confirm uniform distribution material fabric. treated demonstrates excellent flame retardancy self‐extinguishing soaking dry LBL method. In addition, FR‐TENG produces electrical output voltage, current, charge 62 V, 170 nA, 17 nC. Finally, integrated programmed microcontroller unit, where warning LED lights up when some situations occur, followed by on screen initiate rescue operation. This work shows great potential for eco‐friendly based materials lifesaving future.

Abstract Omnidirectional wind energy harvesting has gained increasing attention as a means of harnessing the inherently variable and multidirectional flows encountered in real-world environments. Triboelectric nanogenerators (TENGs), which leverage contact electrification electrostatic induction to convert mechanical motion into electrical power, are particularly well-suited for such applications due their ability operate effectively under low-speed intermittent conditions. In this review, we first outline fundamental triboelectric processes operating modes that underpin TENG functionality, emphasizing how low inertia high-voltage outputs make them compatible with wide range profiles. We then discuss three predominant device classifications—rotary, aeroelastic, rolling-based—highlighting distinct configurations capacities omnidirectional capture. Key examples illustrate strategically designed rotor geometries, flutter-driven films, rolling elements can maximize contact–separation events enhance generation complex airflow patterns. Finally, examine major obstacles faced by TENG-based harvesters, including durability, hybrid system design, intelligent power management. Strategies overcome these barriers involve wear-resistant materials, adaptive architectures, advanced circuitry, offering solutions feasible micro- or off-grid scenarios.
