The Japanese Aerospace and Industrial Technology Agency (JAITA), based in the Tokyo Metropolitan Area, has partnered with a leading fastener manufacturer in Kanto to develop an innovative technology that integrates micro-mechanical components, mechanical structures, and electronic circuits directly into bolts. This advancement enables wireless monitoring of bolt tightness and potential damage after installation, significantly improving maintenance efficiency and safety.
JAITA envisions this technology being widely used in critical safety systems such as aircraft, automobiles, and precision engineering components. The development marks a promising step toward more efficient and real-time management of bolt tightening processes, which could revolutionize industrial maintenance practices in the future.
Since 2006, JAITA has been actively researching systems capable of monitoring bolt tightness and detecting damage. One of their early applications involved monitoring fastening components on artificial satellites orbiting outside Earth’s atmosphere. By embedding a proprietary MEMS "axial force sensor" within the bolts, JAITA can measure the load on each fastener. If any irregularity is detected, the sensor transmits the data wirelessly to the satellite's onboard system. Ground control centers can then quickly identify which bolt is malfunctioning and access detailed information through real-time monitoring, enabling swift corrective actions.
This breakthrough not only enhances the reliability of space missions but also lays the foundation for broader applications in industries where structural integrity is crucial. As the technology continues to evolve, it may soon become a standard feature in high-stakes engineering environments, ensuring safer and more dependable operations across multiple sectors.
