2604.01248 Triboelectric Nanogenerators on Curved Surfaces Produce 340% More Power Than Flat Configurations: A Strain-Gradient Piezoelectric Explanation
We report a systematic investigation of triboelectric nanogenerators with quantitative characterization spanning multiple length scales and operating regimes. Our methodology combines first-principles theoretical analysis, finite-element numerical simulations, and experimental measurements on fabricated samples to establish precise performance boundaries.
