AB - Wearable textile-based triboelectric nanogenerators (T-TENGs) offer a promising platform for wearable energy harvesting and self-powered sensing. In this work, we present a wearable graphene-based T-TENG fabricated via a spray coating technique, where a polyvinyl alcohol (PVA) adhesion layer works to enhance interfacial performance. The graphene/PVA electrode exhibits significantly low sheet resistance of 479.3 Ω square, over four orders of magnitude lower than that of a pure graphene electrode (5.4 MΩ square) maintaining stable electrical performance after more than 300 bending cycles. This graphene/PVA composite layer functions as both the induction electrode and triboelectric layer, combining mechanical robustness and wearability to ensure stable and durable operation of the final T-TENG device. This device also demonstrates strong responsiveness to external pressure and effective signal generation under biomechanical motion. Its conformability and fast response make it well-suited for applications such as rehabilitation monitoring, activity tracking, and emergency response. This work presents a scalable, low-cost fabrication strategy for textile-based TENG and highlights the functional advantages of sprayed graphene/PVA for next-generation wearable electronics.
