The inductors with adjustable surface area for energy harvesting utilization

Abstract

© 2016 IEEE. The concept of energy harvesting has been widely accepted as future necessity for the society, accelerating its transition to the environment of the so-called green technologies. The energy harvesting approaches in various domains of human surroundings have been considered, among them those related to the energy of ambient electromagnetic field (EMF). In this early research paper, the inductor with the adjustable surface area was analyzed, in order to maximize the magnetic flux through its surface and subsequently induced electromotive force (emf). Additionally, the overall inductance of such assemblies can be considerably increased. The case study of simple, planar, rectangular inductor has been examined using partial inductance approach, supported by MATLAB software framework, showing considerable increase in overall inductance of such inductors.
