An Instantly Reconfigurable 2-D Wireless Power Transfer System
Wireless charging pads such as Qi are rapidly gaining ground, but its limited power supply range still requires precise placement on a specific point. 2-D wireless power transfer (WPT) sheets consisting of coil arrays are one well-known solution for this issue. However, these approaches require custom-made designs by experts; what we need is a system that can be reconfigured by simply placing ready-made modules on the intended surface. To solve these issue, we present a reconfigurable 2-D wireless charging system which enables such simple construction of wireless charging surfaces. Our system can instantly and interactively form wireless charging surface on everyday objects (e.g. floor, wall, table, etc.) only by placing resonator modules.
