A Cuttable 2-D Wireless Power Transfer Sheet

For the integration of wireless power transfer (WPT) capabilities into daily objects such as furniture and clothing, people need to design a coil array according to the size and shape of the target surface. However, conventional design procedure has forced tremendous effort and cost, along with specialized knowledge, for designers needed not only to design a proper wiring to fit in the surface but also to consider the inductive interference between the adjacent coils. Thus, we proposed a cuttable WPT sheet that only requires users to cut-and-paste to achieve a diverse shape of WPT surface.

無線電力伝送に用いられるコイルを家具類・衣類などに組み込む場合，対象の意匠を決定した後に，コイル形状を設計・実装する．しかし，現状の複数のコイルを並べる方式では，形状に合わせた配線形状とコイル間の相互干渉を考慮した配置設計が必要であり，高周波回路に関する深い知識と多くの労力・コストが強いられる．そこで，我々はユーザが望む形状に切り抜いて貼り付けるだけで動作する無線電力伝送シートを提案した．
