Triboelectric Self-Powered Sensing Technology for Online Non-Destructive Testing of High-End Equipment
Jianhai Zhang
During high-speed rotation, complex machining, and multi-condition service, high-end equipment places increasing demands on state perception and intelligent diagnosis. Triboelectric nanogenerators, which integrate mechanical energy harvesting with active sensing capabilities, provide a new sensing pathway for online non-destructive testing of equipment. This presentation focuses on triboelectric self-powered sensing technology and introduces its applications in rotating machinery health monitoring, CNC machine tool process state perception, surface quality evaluation, and complex defect identification, providing new technical support for predictive maintenance and intelligent operation and maintenance of high-end equipment.

Development of Structural Health Monitoring Technologies and High-Performance Durable Structures for Marine Engineering Applications
Xianwen Hu
Offshore engineering structures are developing rapidly, but steel and steel-reinforced concrete components suffer from severe corrosion, threatening operational safety and service life. This creates an urgent need for advanced structural health monitoring (SHM) technologies and durable structural systems. This study addresses these needs by developing two complementary solutions: a guided wave-based SHM method for submerged components and a hybrid FRP-UHPC tubular member. The SHM method excites guided waves in unsubmerged regions, which propagate into submerged zones and detect damage via scattering signals, offering wide coverage and high sensitivity to minor defects. Limitations and potential applications of the technique are analyzed. The FRP-UHPC tubular member, tailored for offshore wind turbine towers and other marine applications, leverages the high performance and durability of FRP and UHPC and is well-suited for harsh marine environments. A number of experimental and analytical tests confirm the member's excellent mechanical performance under compression, flexure, and torsion. Additionally, preliminary tests were conducted and found that guided waves propagate over meter-scale distances in the composite members and are highly sensitive to fatigue damage evolution. This work demonstrates that the proposed SHM method and FRP-UHPC tubular members are promising technologies for improving the safety and durability of offshore engineering structures.
