我们提出了一种可弯曲的无线电力传输板，允许用户修改其大小和形状。这种直观的操作允许用户轻松地将无线电力传输功能添加到日常物品中。板材的薄度、柔性和轻盈等特性使我们的板材与各种配置高度兼容。我们提供了一套技术原则的电路设计，它集成了H树布线和时分供电技术。H树布线允许板即使从板的外部切割时也保持功能性，而时分电源避免了由相邻发射器线圈之间的磁干扰引起的功率传输效率的降低。通过评估，我们发现，我们的时分供电方案减轻了功率传输效率的下降，并成功地提高了平均效率。此外，我们提出了四个应用程序，将我们的表集成到日常物品：无线充电家具，包，夹克和工艺品;这些应用程序证实了我们的原型的可行性。
We propose a cuttable wireless power transfer sheet which allows users to modify its size and shape. This intuitive manipulation allows users to easily add wireless power transmission capabilities to everyday objects. The properties of the sheet such as thinness, flexibility, and lightness make our sheet highly compatible with various configurations. We contribute a set of technical principles for the design of circuitry, which integrates H-tree wiring and time division power supply techniques. H-tree wiring allows the sheet to remain functional even when cut from the outside of the sheet, whereas time division power supply avoids the reduction in power transfer efficiency caused by the magnetic interference between adjacent transmitter coils. Through the evaluations, we found that our time division power supply scheme mitigates the degradation of power transfer efficiency and successfully improves the average efficiency. Furthermore, we present four applications which integrates our sheet into daily objects: wireless charging furniture, bag, jacket, and craft; these applications confirmed the feasibility of our prototype.
