Abstract Triboelectric nanogenerators (TENGs) have recently emerged as a promising technology for efficient water wave energy harvesting. However, there is paucity of clear guidance regarding the optimal designs TENGs and their shells to achieve absorption conversion in real random waves. Herein, from perspective wave‐body interaction transfer, this paper proposes structural quality factor (Q unit ) quantitative evaluation both motion floating triboelectric nanogenerator (Flo‐TENG) capability absorb convert efficiently. The further subdivided into amplitude acc ), which characterizes shell amplitude, frequency f describes frequency. This systematically investigates impact various parameters such bow shapes, curvatures, inclinations, immersion ratios on Q . findings indicate that variations shape result distinct values along different axial directions propagation. These directly influence efficiency these directions. results provide fundamental design high‐performance Flo‐TENG selection internal harvesting enable more conversion.
