AI Technical Summary

Problems solved by technology

Even electronic devices that are slightly misaligned with the inductive charging base station or that have moved slightly, such as due to vibrating user warnings, etc., may not be able to charge
Due to heat dissipation, available space, and other design considerations, inductive charging base stations are limited in the number of coils they can add to improve performance

Abstract

A laminate includes multiple paper layers, with at least one induction coil comprising first and second sets of windings. Two or more paper layers include the sets of windings comprising an electrically-conductive material. The sets of windings may be distributed throughout the laminate layers and provide good wireless induction charging performance in a compact space.

Description

technical field [0001] none. Background technique [0002] Wireless inductive device charging is a technology that uses near-field wireless transfer of energy between two coils tuned to resonate at the same frequency. With one coil located in the inductive charging base station, another coil located in the electronic device can receive the transmission of energy to wirelessly charge its battery. Wireless charging is highly desirable because consumers can easily charge devices when and where they need them. Additionally, wireless charging eliminates the need for different chargers for different devices. [0003] Inductive charging base stations typically require precise alignment between the two coils to perform energy transfer of sufficient power to charge electronic devices. Even an electronic device that is slightly misaligned with the inductive charging base station or that has moved slightly, such as due to vibrating user alerts, etc., may fail to charge. Due to heat...
