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.
