بررسي عملكرد ساختارهاي استوانه اي ترايبوالكتريك با هدف استفاده در ساختارهاي تاري-پودي

Triboelectric nanogenerators (TENGS) are innovative structures that convert mechanical energy into electrical energy through the triboelectric effect an‎d electrostatic induction. One of the growing areas of development is textile-based triboelectric nanogenerators (T-TENGS), which integrates energy harvesting capabilities into textile structures. In this study, six different cylindrical core yarn structures with various material combinations an‎d layer arrangements were designed, fabricated, an‎d eva‎luated. The results showed that the multilayer structures, especially the multilayer concentrated yarn structure with PP rubber core an‎d PVDF steel shell, showed superior performance in all major indicators. This structure had the best performance among the experimental samples with an output voltage of 14/42 V, peak-to-peak power of 1.26 mW, an‎d a signal-to-noise ratio of over 150. Also, the combination of flexible rubber core with suitable polymer coatings significantly increased the average harvested energy of 286 nJ an‎d improved the signal quality. The physical an‎d mechanical properties of the materials played an important role in the performance of the structures. The hardness of the glass resulted in higher SNR an‎d sharper pulses, while the flexibility of the rubber increased the contact area an‎d harvested energy. The triboelectric contrast between PVDF an‎d PP also resulted in higher voltage generation. The results of this study indicate that a multilayer design with appropriate material selec‎tion an‎d structural geometry can significantly improve the performance of yarn-based triboelectric nanogenerators.
