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.

Underwater ultrasonic detection is critical for marine security, playing a vital role in resource development, environmental protection, and national defense. However, existing systems, which primarily rely on active scanning technologies, are hindered by high costs, significant energy demands, challenges achieving large-scale deployment. Here, we introduce microfiber-based triboelectric acoustic sensor (MTAS) featuring core-shell hierarchical structure, offering self-powered solution precise measurement of underwater ultrasound source distance. By leveraging the principles contact electrification/triboelectrification electrostatic induction, MTAS efficiently converts complex vibrations into real-time electrical signals. The demonstrates rapid response times as low 8.6 μs, signal-to-noise ratio 29.8 dB, capability to detect sources with power levels above 1.6 W via time-difference-of-arrival analysis. To address sea applications, further propose distributed network that integrates multiple units capable localization motion trajectory visualization. This innovation represents transformative approach, combining operation, ease deployment, imperceptibility, paving way large-area, energy-efficient submarine security systems. Such advancements redefine paradigm target detection, aligning technological pressing demands safety sustainability.
