Energy Harvesting From Electric Power Line: A Brief Review

Yunus Uzun, Taguchi Kozo


Energy harvesting systems are used with or instead of batteries to provide energy to low power devices such as sensors and sensor nodes. The most commonly used energy harvesting systems are those that obtain electrical energy from vibration. Because vibrations can be found intensively in the environment. In this study, the systems that produce energy by means of various circuits attached around wires carrying electrical energy are examined. These are generally piezoelectric and electromagnetic energy harvester systems. In the studies, the effects of the distance, the magnitude of the current flowing through the wire and the load resistance to be connected to the energy harvester were investigated. In addition, permanent magnet arrays have been used to increase the amount of power to be obtained in some applications.
