However, a decline in performance was noted after week 4 (W4). This decrease was attributed to issues such as the residual adhesiveness of Kapton tape leaving contamination on the graphene layer, leading to reduced adhering and reduced charge accumulation. Additionally, continuous bending and stress caused surface cracks that confirm from scanning electron microscopy (SEM) images, elevating sheet resistance and parasitic capacitance and further decreasing the output results (Figure , supporting information). Additionally, the environmental humidity also impacts the device's performance by facilitating the adherence of water molecules to the triboelectric surface. This adherence leads to the dissipation of charge, thereby reducing the charge density on the material surface and consequently compromising the device's output performance. However, Despite these challenges, the decreasing ratio with time is observed smaller after W5, and even after seven months, these devices still retain the ability to generate around 45% of the peak results achieved after W3 (Figure , supporting information), demonstrating the high durability of the fabricated T-TENG.
