Abstract Planetary gearboxes, a critical component in industrial transmission systems, present significant challenges for condition‐monitoring technologies owing to their complex motion characteristics. Traditional monitoring methods are often susceptible environmental noise interference and rely on external power supply complicating maintenance increasing costs. This study presents an situ sensing system planetary gearboxes using floating freestanding‐layer‐mode triboelectric nanogenerator (FF‐TENG) integrated the side of planet gear. By utilizing inherent axial micromotion characteristics during operation, employs floating‐electrode structure with adaptive gap adjustment prevent contact wear between electrode dielectric layer, which significantly enhances durability. Key parameters systematically analyzed examine FF‐TENG's output working mechanism. The FF‐TENG exhibited outstanding speed‐monitoring capabilities across diverse rotational speeds. Furthermore, local maximum mean discrepancy improved transformer encoder model is designed. achieved 98.4% accuracy fault diagnosis different speeds modes. Then, applied gearbox robotic arm, realizing its behavior. research introduces self‐powered TENG, providing new approach rotating machinery sensing.

Abstract With advances in automation and intelligent manufacturing, where mechanical vibration monitoring has become critical for equipment health assessment, a high‐sensitivity triboelectric sensor using carbon nanotube (CNT)‐modified conductive sponge architecture is proposed. The developed consists of porous matrix uniformly coated with solution fluorinated ethylene‐propylene (FEP) film. Systematic characterization revealed that the CNT‐functionalized exhibited remarkable enhancement output voltage (ΔV = 204% at 80 m −1 s 2 acceleration) compared to original counterparts, demonstrating superior sensitivity (4.47 mV m⁻¹ ) across an extended acceleration range (5–80 ). optimized structural configuration (0.1 mm gap, 0.5 thickness) enabled broadband frequency detection from 1 500 Hz. In durability test up 216 000 working cycles, its remains stable, showing no significant attenuation or drift. Moreover, tests conducted on marine such as blowers air compressors further validate sensor's precise capability, measured highly matches actual vibration. This research provides new ideas sensing technology expected be widely applied industries manufacturing shipping, contributing upgrading sustainable development various industries.
