Abstract
Long-term structural health monitoring (SHM) systems using wireless smart sensors for civil infrastructures such as cable-stayed bridges has been researched due to its cost-effectiveness and ease of installation. Wireless smart sensors are usually powered by high capacity batteries because they consume low power. However, theses batteries require regular replacements for long-term continuous and stable operation. To overcome this limitation of wireless smart sensor-based SHM, considerable attention has been recently paid to alternative power sources such as solar power and vibration-based energy harvesting. Another promising alternative ambient energy source might be a wind-generated power; in particular, it can be very useful for structures in windy area such as coastal and mountainous area. In this study, the feasibility of the wind-powered generation for wireless smart senor nodes is investigated by through experimental and analytical approaches, and the possibility of practical application to actual SHM system of a cable-stayed bridge is discussed.
