Future wearable electronics require sustainable power sources, and nanogenerators offer promising solutions to convert ambient mechanical energy to electricity while ensuring flexibility, durability, and practical deployment. This work demonstrates a textile-based piezoelectric nanogenerator (T-PENG), which is a durable and scalable energy-harvesting system, using the inherent strength of 2D materials to elevate the performance metrics significantly. Screen printable 2D graphene ink was used for developing the textile-based flexible electrodes. The composite layer was prepared using zinc oxide (ZnO) enclosed molybdenum disulfide (MoS2) (MoS2@ZnO) and a screen printable paste. The incorporation of 2D MoS2 into the T-PENG system significantly enhances its output performance. This improvement is further validated by COMSOL computer simulations, which align closely with the experimental findings. At 10 wt% of MoS2, d33 value of our device reaches ~5.67 pC N−1, an approximately threefold improvement over the MoS2-free device. Furthermore, T-PENG resulted in a significantly high open-circuit voltage (Voc) of ~60 V, and a peak power density (J) of 126.84 mW m−2. Moreover, T-PENG demonstrates high durability and flexibility while retaining ~92% of its output power over 3 months and sustaining ~90% efficiency after 500 bending cycles. T-PENG demonstrated the ability to power over 60 blue light emitting diodes (LEDs) and functions as a self-powered sensor. These advancements position MoS2 as a significant material for next-generation multifunctional smart textiles.
