Abstract :
In this paper, capacitive and inductive energy harvesting devices are proposed to extract energy from the electric and magnetic fields surrounding 132kV overhead transmission lines. Research has been done to determine what parameters affect these energy harvesters. In-lab testing has been done on both the inductive and capacitive energy harvesters and results look promising. A single IC solution for 3.3V voltage regulation and energy storage was also tested.
