A nanoscale approach in wireless power transfer — •Marius Wodniok and Sonja Schöning — University of Applied Sciences Bielefeld, Bielefeld, Germany

Inductive applications become an every day tool in electronics and electronic parts as for example in phones and cars. In that matter the wireless power transfer needs to get optimized in concerns of speed, efficiency and (more important) displacement tolerance. Therefor it is essential to guide the magnetic field lines and form a focused stray field. In heating applications power transfer shall additionally occur homogenous corresponding to flat receivers like cooking dishes.

To realize these demands and make a nanoscale approach a material study for surrounding and receiving parts is performed to determine the key material characteristics for an optimized wireless power transfer. Beforehand simulations using COMSOL Multiphysics are run for a simplified system of an induction stove to predefine key characteristics and narrow down the selection of suitable materials. The material study itself includes measurements of the magnetic, electric and thermal properties in correlation to the power transfer. Following these investigations, nanoparticles and thin films will be tailored for an optimized wireless power transfer.
