Description
ここで、Zre(f)は、共振インピーダンスの実部であり、Zim(f)は、共振インピーダンスの虚部である。特定の実施形態では、センサーのインピーダンス応答は、2つ以上の周波数がセンサーの共振を横切ってセンサー応答を測定するために利用されうるため、多変数応答でありうる。特定の実施形態では、センサーのインピーダンス応答は、2つ以上の周波数がセンサーの共振ピークの外側のセンサー応答を測定するために利用されうるため、多変数応答でありうる。いくつかの実施形態では、センサー応答は、センサーの共振を横切って複数の周波数において測定される。例えば、センサーが約1MHzで共振する場合、測定周波数及び関連のセンサー応答は、約0.25MHzから約2MHzまで測定される。この多変数応答が、多変量解析によって分析される。センサーの多変数応答は、センサーの全インピーダンススペクトル並びに/或いはFp、Zp、Fz、F1、F2、Z1、及びZ2など(ただし、これらに限られるわけではない)のいくつかの個別に測定された特性を含む。図9が、本発明の技術の実施形態に従って共振センサーの実施形態について測定されたインピーダンスパラメーターのグラフを示している。これらの測定された特性及び他の測定された特性が、「スペクトルパラメーター」である。これらの特性は、インピーダンスの実部の最大値の周波数(Fp、共振ピーク位置)、インピーダンスの実部の大きさ(Zp、ピーク高さ)、ゼロリアクターンス周波数(Fz、インピーダンスの虚部がゼロである周波数)、インピーダンスの虚部の共振周波数(F1)及びインピーダンスの虚部の反共振周波数(F2)、インピーダンスの虚部の共振周波数(F1)における信号の大きさ(Z1)、並びにインピーダンスの虚部の反共振周波数(F2)における信号の大きさ(Z2)を含む。他のパラメーターを、例えば共振のQ値、位相角、及びインピーダンスの大きさなど、全インピーダンススペクトルを使用して測定することができる。多変数応答スペクトルパラメーターは、ここでの言及によってその全体があらゆる目的で本明細書に援用される「RFIDセンサーの較正のための方法及びシステム(Methods and systems for calibration of RFID sensors)」という名称の米国特許第7911345号に記載されている。
