Orientation insensitive power transfer by magnetic resonance for mobile devices

The efficiency of wireless power transfer (WPT) from an orientation insensitive system to a mobile device by strongly coupled magnetic resonance (SCMR) is reported here. This paper compares an optimal loop-based design in standard SCMR systems with misalignment insensitive system (3D and 3loop structure), which exhibits higher efficiency than typical SCMR devices in several directions in a sphere.
