The energy conversion efficiency of a triboelectric nanogenerator (TENG) is severely limited by the charge density materials, while drastic and unavoidable decay happens during contact due to insufficient retention capacity positive materials. Here, elaborately synthesized acid-ion-doped pyridine-based polybenzimidazole processing with strong capability demonstrated couple negatively corona-polarized electrets. As illustrated thermal stimulation an ion mass spectrometer, formation acid-ion chimerism processes high activation for stored charges, selective anion migration can compensate escape polarized charge. Accordingly, reach up 596 μC m–2 rate reaches 49.7%, which so far highest intrinsic obtained in open air. Thus, ionic strategy provides effective way suppress escaping air gives great expandable avenue material challenges TENG's practical deployment.

Lightweight, easily processed, and durable polymeric materials play a crucial role in wearable sensor devices. However, achieving simultaneously high strength toughness remains challenge. This study addresses this by utilizing an ion-specific effect to control crystalline domains, enabling the fabrication of triboelectric material with tunable mechanical properties. The dense crystal-domain cross-linking enhances energy dissipation, resulting boasting both tensile (58.0 MPa) (198.8 MJ m–3), alongside remarkable 416.7% fracture elongation 545.0 MPa modulus. Leveraging these properties, is successfully integrated into self-powered devices, real-time feedback on human joint movement. work presents valuable strategy for overcoming strength-toughness trade-off materials, paving way their enhanced applicability broader use diverse sensing applications.
