The supply of electrical power is indispensable in the internet of things (IoT) area. Triboelectric nanogenerators (TENGs) has been largely used as a power supply due to simple device structure and various possibilities of material selection. Although various surface modifications of TENG are utilized for improving the output performance of TENG, these methods have significant drawbacks of high-cost fabrication process, limited device size, and wearing out. Here, a mechanically robust TENG using a newly developed surface-textured glass fabric reinforced siloxane hybrid film (SGH film) is presented. The large-scale SGH film is cost-effectively fabricated via a simple roll-to-plate and UV curing process. The film is repeatedly duplicated over 100 times using one pre-treated substrate mold. SGH film exhibits superior thermal and mechanical stability, compared to other polymer films. Finally, surface textured TENG (THTENG) is achieved using extremely stable SGH film, resulting in enhanced output power compared to flat TENG and high durability during the 100 000 cycles of TENG operation.
