AB - Wearable textile triboelectric nanogenerators (T-TENGs) offer a promising platform for wearable energy harvesting and self-powered sensing. In this work, we present a wearable spray-coated graphene-based T-TENG, in which a polyvinyl alcohol (PVA) adhesion layer serves to enhance the interfacial performance. The graphene/PVA textile (Gr/PVA-Tex) electrode exhibits a significantly low sheet resistance of 479.3 Ω <sup>−1</sup>, which is over four orders of magnitude lower than that of a pure graphene textile (Gr-Tex) electrode (5.4 MΩ <sup>−1</sup>), while maintaining stable electrical conductivity after more than 1000 bending cycles. The graphene/PVA layer functions as both the electric induction electrode and triboelectric component, enhancing the wearability by increasing the average total strain by 60.5% while maintaining the ultimate tensile strength in both warp (103.3 MPa) and weft (48.6 MPa) directions. This mechanical reinforcement ensures stable and durable performance of the T-TENG device. The device was optimized for simultaneous pressure (with area-normalized sensitivity of 0.176 kPa<sup>−1</sup> cm<sup>−2</sup> from 9.8 to 120 kPa and 0.003 kPa<sup>−1</sup> cm<sup>−2</sup> from 120.0 to 318.5 kPa) and biomotion sensing, making it well-suited for applications such as rehabilitation monitoring, activity tracking, and emergency response. This work presents a facile, low-cost fabrication strategy for T-TENGs and highlights the functional advantages of sprayed graphene/PVA for next-generation wearable electronics.
