Recycling plastic waste into triboelectric nanogenerators (TENGs) presents a sustainable approach to energy harvesting, self‐powered sensing, and environmental remediation. This study investigates the recycling of polyvinyl chloride (PVC) pipe polymers nanofibers (NFs) optimized for TENG applications. We focused on optimizing morphology recycled PVC polymer NFs enhancing their piezoelectric properties by incorporating ZnO nanoparticles (NPs). The PVC/0.5 wt% were tested with Nylon‐6 NFs, copper (Cu) electrodes. exhibited power density 726.3 μW cm −2 —1.13 times higher than Cu maintained 90% stability after 172 800 cycles, successfully powering various colored LEDs. Additionally, 3D‐designed device was developed harvest from biomechanical movements such as finger tapping, hand foot pressing, making it suitable wearable automatic switches, invisible sensors in surveillance systems. demonstrates that devices can effectively address energy, sensor, challenges.

Abstract The droplet triboelectric nanogenerator (D‐TENG) harnesses energy from natural water droplets, though its performance and lifespan can be compromised by contamination on the functional layer. Water molecules have a strong affinity for polymer surfaces, which increases surface tension sliding‐off angle, leading to greater adhesion. As these droplets evaporate, they leave behind residues, such as calcium (Ca) magnesium (Mg) salts, that obscure surface, thereby diminishing electrification area altering dynamics—resulting in decreased electrical output. This study presents micro‐nanostructured D‐TENG with advanced anti‐fouling capabilities. By adding layer of metal nanoparticles followed ion etching fluorination grafting, retention accumulation are effectively minimized. demonstrates fourfold increase output compared predecessor. Following 10 000 interactions, original drops 53%, whereas variant only experiences 7% reduction. These enhancements provide significant insights applications contribute development strategies.
