Printable and Conformal Strongly Coupled Magnetic Resonant systems for wireless powering

Abstract

In this paper, a printable compact Conformal Strongly Coupled Magnetic Resonance (CSCMR) method for wireless powering is proposed. This new wireless power transfer method uses printed planar transmitter and receiver configurations on substrates to shrink the volume down to λ <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</inf> /66. Also, self-resonant spirals, which do not need lumped capacitors to achieve resonance, are designed for our novel CSCMR systems. This simplifies the fabrication process of SCMR systems and repeatable designs can be easily achieved. The efficiency of our proposed methods is validated using measurements and simulations. Our proposed designs can be incorporated easily on PCBs and added onto modern handheld devices.
