Srikulnath Nilnoree, a PhD candidate in Structural Engineering Program at the School of Engineering and Technology, AIT, has made significant strides in the field of Structural Health Monitoring (SHM) under the guidance of Prof. Attaphongse Taparugssanagorn. Srikulnath Nilnoree was also selected as an exchange student (October 2023 to March 2024) at the University of Tokyo. Srikulnath successfully published her Research on the implementation of a synchronous Structural Health Monitoring (SHM) framework utilizing wireless, low-cost, and off-the-shelf components. SHM is a field focused on continuously assessing the condition of structures—like buildings, bridges, and dams—to detect any potential problems before they become serious.
What sets Srikulnath’s work apart is her use of advanced, yet cost-effective technologies to create a system that is both accessible and highly effective. Her system uses small, low-cost sensors that can be placed on different parts of a structure to monitor things like vibrations and movements. These sensors are connected through a method called TCP/IP socket programming, which allows them to “talk” to each other and synchronize their data collection. This synchronization is crucial because it ensures that all the data collected from different sensors is accurate and can be used to get a complete picture of the structure’s health.
Srinulnath also incorporated ideas from the Internet of Things (IoT), which is a technology that allows devices to connect and communicate over the internet. This means her system is not only cost-effective but also scalable and flexible, making it useful for a wide range of applications.
One of the most impressive aspects of this research is how it democratizes access to advanced monitoring technology. By using off-the-shelf components and clever programming techniques, Srikulnath’s system makes it possible for more people to deploy SHM systems, especially in areas where budget constraints might have previously made it impossible.
The application of Srikulnath Nilnoree’s research on Structural Health Monitoring (SHM) spans across multiple engineering and infrastructure sectors, offering significant advancements. Her research presents a cost-effective and scalable method for monitoring the structural health of critical infrastructure such as bridges, buildings, and dams. By ensuring precise time synchronization and real-time data collection, this system allows for the early detection of potential structural issues, helping to prevent catastrophic failures and extend the lifespan of these structures. In aerospace engineering, the ability to monitor the integrity of aircraft structures in real-time is crucial, and Srikulnath’s SHM system could be adapted to develop low-cost, reliable monitoring systems that ensure safety and reduce the risk of in-flight failures.
Beyond traditional infrastructure, this SHM framework is also adaptable to environmental monitoring applications, such as assessing the stability of levees, seawalls, and other protective structures affected by environmental changes like erosion or flooding. As cities evolve into smart urban areas, the research can contribute to the development of smart infrastructure that continuously monitors its own health, particularly in new buildings and transportation networks. Additionally, in disaster management scenarios, the SHM system can provide critical data before, during, and after natural disasters, aiding in rapid damage assessment and emergency response. The research is also relevant to renewable energy, where it can help monitor the structural integrity of wind turbines and solar panel arrays, ensuring their safety and efficiency. By making advanced SHM more accessible, Srikulnath’s work promotes safer and more resilient infrastructure.
In summary, Srikulnath Nilnoree’s research is not just a technical achievement; it’s a practical solution with real-world applications. Her work makes it easier and more affordable to ensure the safety and longevity of the structures we rely on every day, contributing to safer, smarter, and more sustainable communities around the world.
Through its focus on enhancing structural health monitoring, this research contributes to several Sustainable Development Goals (SDGs), including Goal 9: Industry, Innovation, and Infrastructure, by fostering technological innovation and infrastructure development. Additionally, it aligns with Goal 11: Sustainable Cities and Communities, by promoting safer and more resilient infrastructure. Furthermore, by enabling more efficient infrastructure management and maintenance, it indirectly supports Goal 3: Good Health and Well-being, by reducing the risk of infrastructure-related accidents and failures.
The National Electronics and Computer Technology Center (NECTEC) and the National Science and Technology Development Agency (NSTDA) supported this research. Their funding and sponsorship have played a crucial role in advancing innovation and research in the field of Structural Health Monitoring, enabling the development of practical solutions with real-world impact.
