A Low-Complexity Power Maximization Strategy for Coulomb Force Parametric Generators

Energy harvesting (EH) is the process of capturing and storing energy from external sources or ambient environment. The EH devices have found various emerging applications, particularly, in healthcare sector. Kinetic-based micro energy-harvesting a promising technology that could prolong lifetime batteries small wearable implantable devices. In this paper, using mathematical model Coulomb-force parametric generator, we analyze dependency output power on electrostatic force micro-harvester. We propose low complexity strategy to adaptively change order maximize harvested power. Simulation results human acceleration measurements confirm effectiveness proposed strategy.
