Wireless Energy Transfer Through Magnetic Reluctance Coupling

open access: yesJournal of Physics: Conference Series, 2014
Energy harvesting from human motion for body worn or implanted devices faces the problem of the wearer being still, e.g. while asleep. Especially for medical devices this can become an issue if a patient is bed-bound for prolonged periods of time and the internal battery of a harvesting system is not recharged.

Modeling of spatial uncertainties in the magnetic reluctivity [PDF]

open access: yesCOMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2017
Purpose The purpose of this paper is to present a computationally efficient approach for the stochastic modeling of an inhomogeneous reluctivity of magnetic materials. These materials can be part of electrical machines such as a single-phase transformer (a benchmark example that is considered in this paper). The approach is based on the Karhunen–Loève
