Triboelectric nanogenerators (TENG) have great potential to help enhancing the energy efficiency of buildings, and thus contribute significantly reduction global greenhouse gas emissions. However, there are major barriers against adoption such emerging technologies. Meeting need for sustainable large-scale fabrication high-performance products remains a critical challenge towards real-world TENGs' building applications. To mitigate this challenge, we enhance poor polarizability native wood by scalable plasma treatment, facile approach which greatest degree preserves wood's warm colors, mechanical robustness while efficiently triboelectric output. We demonstrate enhancement electric output assembling (W-TENGs) in both contact-separation single-electrode operation modes. show that when two radial-cut samples (L × R T: 100 80 1 mm3), one treated with an O2 other C4F8 + plasma, subjected periodic contact separation applied pressure as low 0.0225 MPa, maximum voltage 227 V current 4.8 µA produced. Eventually, showcase applicability our prototypes floors, opening up new technological pathways 'net-zero emissions' future.
