ABSTRACT
This chapter introduces a variety of energy harvesting (EH) technologies using several typical energy sources. It provides a brief review of these EH techniques for the health monitoring of civil structures. The chapter also introduces several interesting applications, which include an EH system using the wind-induced vibration of a stay cable to power a wireless sensory system, the long-term testing of a vibration-based EH system for the health monitoring of bridges and a self-powered strain sensor for damage detection. It also provides overviews of vibration control systems integrated with EH systems. K. M. Farinholt et al. presented experimental investigations using EH and wireless energy transmission to power wireless structural health monitoring sensor nodes. The optimal damping coefficient for passive vibration control and for energy harvesting is discussed based on the analytical solutions. The world has enormous potential for wind energy, which can be utilised for electricity generation in a sustainable and clean manner.
