My work focuses on Structural Health Monitoring (SHM) solutions for pedestrian footbridges, focusing on real-time, automated systems powered by self-sustaining Wireless Sensor Networks (WSNs). By harvesting energy from footbridge vibrations, my work eliminates batteries, reducing maintenance and environmental impact. This approach enables continuous monitoring, early detection of structural issues, and valuable usage data to aid infrastructure planning, combining technological innovation with tangible benefits for communities and the environment.
