ABSTRACT
ABSTRACT Prevention and monitoring of corrosion related degradation of pipelines is an important and established topic. Various corrosion monitoring techniques exist, and battery powered wireless sensors are now being employed for these techniques. Due to the limited lifetime of batteries, there has been a recent and growing interest in powering these sensors with energy harvested from the ambient environment, leading to the potential of energy harvesting monitors for such purposes. This paper attempts to outline the potential of energy harvesting based corrosion monitoring, and provides a context around existing methods and technologies. An overview of the conventional corrosion monitoring techniques is presented, followed by a consideration of the energy harvesting technologies with a focus on vibration energy harvesting. Finally, existing research conducted around harvesting based monitoring of pipes are considered to highlight the potential evolution of this technology for Structural Health Monitoring (SHM) purposes.
