Abstract Conventional triboelectric generators (TEGs) have been developed to mainly harvest the energy of linear mechanical motions and convert it usually into oscillating or pulsive, but not sustainable, electrical outputs. In this study, unidirectional charge transfer mechanisms are introduced develop a metamaterial (TMM) with sustainable Density functional theory experimental analyses demonstrate three minimum necessary components TMMs fabricated by only two materials (i.e., copper PTFE) generate Under wide range compression‐tension strain ±50%, maximum open‐circuit voltage, short‐circuit current, volumetric power density 3860 V, 8 µA, 365.3 kW m −3 , respectively. Different from most conventional cellular solids, dissipation increases quadratically unit cell number. High electromechanical efficiency is achieved when miniaturized. addition harvesting dissipation, can sense displacement counting number distinctive peaks in reaction force versus time curves. The extreme functionalities facilitate their applications intelligent suspension systems, miniaturized green sources, self‐sensing harvesters.

A poly(ethylene terephthalate) (PET) nonwoven‐fabric‐based triboelectric nanogenerator (NWF‐TENG) with high energy‐harvesting efficiency at ultralow contact frequencies is introduced, enabled by the concept of pseudo‐thickness. PET‐based NWF exhibits consistent mechanical properties regardless its origin, even including recycled PET sources, providing sustainable benefits NWF‐TENG system. Above all, this study first demonstration to analyze impact thickness changes in compressible dielectric materials within dielectric‐to‐dielectric TENG models. Through RC decay analysis, it revealed that peak‐to‐peak voltage NWF‐PET 2,653 V, significantly higher than conventional noncompressible film‐based (F‐TENG). After combining a power management system, achieves continuous direct current output 24.8 mW m −2 , indicating potential for powering electronic devices. Lastly, outstanding charge preservation capability due sustained state during compression cycles material. In an application test, stopwatch continuously powered 0.0025 2 operating frequency 0.2 Hz. work, valuable insights are provided into design and optimization energy harvesting systems using compressing valid pseudo‐thickness concept.

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.
