The proposed setup features two flat, horizontal rotating discs, each connected to a different voltage amplitude. This design is intended to separate aluminum (Al) and copper (Cu) metals from a ternary mixture of aluminum, copper, and PVC (Al/Cu/PVC). The metallic particles moving under the two discs, placed in cascade, are attracted toward the first or the second disc depending on their weight. The first disc is intended to attract light aluminum particles, whereas the second disc with a higher voltage attracts copper particles. The required voltage for aluminum is approximately 5 kV, nearly the half of the required voltage for copper, which is 11 kV. Once the particles are attracted to the discs, they are radially ejected when they reach its surface. The collecting boxes, located on both sides of the discs, capture the separated materials. The separator is equipped with five boxes: two for aluminum, two for copper, and one for PVC, which remains on the conveyor and is recovered at the end. The separator is modeled and optimized using the design of experiments methodology. The main influencing factors were the voltages and the rotation speeds of the two discs.

By incorporating LED indicators into each PC-TENG and measuring the output voltage, it is a simple and straight way to detect the presence of loose bolts and to identify their specific locations. Moreover, the possibility by only measuring the combined output voltages of TENG sensors was studied, and it was found that the TENG sensors with different output voltages were suitable for the multiple bolts detection, while the ones with similar output voltages cannot be employed for the multiple cases. The inconsistence of TENGs output results was often seen as a disadvantage, but in this work, we innovatively leveraged this behavior to enable multiple bolts loosening detection. By creatively utilizing distinct voltage outputs and integrated LED indicators, this PC-TENG system achieves simple, real-time identification of loose bolts in multi-bolt setups, offering a novel strategy for structural health monitoring in practical applications.</div></div>","PeriodicalId":54842,"journal":{"name":"Journal of Electrostatics","volume":"135 ","pages":"Article 104093"},"PeriodicalIF":1.9,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144099597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
