Summary:PROBLEM TO BE SOLVED: To provide systems, device, and methods for sensing and controlling a resonance condition of a wireless power system.SOLUTION: A device for resonant frequency tuning includes a coil L1 for transmitting wireless power. The device further includes an element Cp to selectively modify a resonant frequency of a transmitter according to at least one of inserting the element into the transmit coil and inductively coupling the element to the transmit coil. 【課題】無線電力（wireless power：ワイヤレスパワー）システムの共振状態を検知及び制御するシステム、装置、方法を提供する。【解決手段】共振周波数の同調する装置は、無線電力を送信するためのコイルＬ１を含む。更に、送信コイルに素子Ｃｐを挿入すること、及び送信コイルに素子を誘導的に連結することの内の少なくとも１つに従って、選択的に送信機の共振周波数を修正するための素子を含む。【選択図】図７
