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.

Tactile sensors are the cornerstone of modern technology development by mimicking human tactile perception and providing precise diverse mechanical feedback for cutting-edge fields such as robotics, medical equipment, virtual reality. However, current research predominantly concentrates on monitoring normal forces. How to accurately recognize decouple multidirectional force pairs remains a challenge. To this end, we design sensor modifying cuprous oxide (Cu2O) surface zinc nanorods (ZnO NRs) arrays integrating it with transverse force-to-vertical conversion structure. As result, modification boosts piezoelectric output ZnO sensitivity 17.25 nA MPa-1, which is about 3 times higher that pure ZnO. The mechanism underlying enhancement illustrated from perspective surface-engineered heterojunction. On basis, ability detect forces verified prototype, can monitor in 12 directions over 360° range. This work provides new strategy designing sensors, showing broad application prospect human-machine interaction beyond.
