本発明のシステムは、匂いサンプル、すなわち特定の場所の大気中の匂い要因と相互作用する少なくとも2つ以上のセンサーを含む作用アレイ部と、作用アレイ部で匂い原因物質に反応したパターンを処理するセンサーデータ処理部と、該匂い情報および該匂いの作用パターン情報をあらかじめ格納している匂い要因情報格納部と、及び該センサーデータ処理部で処理されたパターンと匂い要因情報格納部の情報とを参照し、その作用パターンに基づいて該匂いを識別するパターン識別部と、を備える嗅覚システムである。
「匂い原因物質」とは、匂いを構成する特定の分子・化合物を意味する。
「匂い要因」とは、匂い原因物質を複数含み、その匂い特有の構成を有する物質群を言う。
まず鼻から匂い要因が入ると、鼻腔最上部の嗅上皮と呼ばれる特別な粘膜に匂い原因物質が溶け込み感知され、嗅上皮にある嗅細胞が電気信号を発生、電気信号が嗅神経、嗅球、脳(大脳辺縁系)へと伝達し、匂い感覚が起きる。
したがって、「匂い」がどのように鼻と相互作用して特定の情報として検出されるか、を模擬していることを特徴とするセンサーであって、「匂い原因物質」を個別に特定することにより「匂い」を特定するとする従来技術とは原理が異なる。
1a.嗅覚システム
本発明にかかる匂い識別システム100は、サンプル情報取得部110、通信手段120、情報処理部130から構成される。
センサーの数は少なくとも2つ配置させるため、匂い要因に含まれる複数の匂い原因物質をについてそれぞれ特異的に検出することが可能となる。
各センサーにおける検出感度を変える等することで測定対象とする匂い原因物質の濃度等も測定することが可能である。
つまり、サンプル情報取得部110で取得、作用、センサーデータ処理されたサンプル物質に関する情報は、情報手段120を通じて情報処理部130へと送信され、当該システムサーバにおいて当該センサーデータ処理パターンと匂い要因情報格納部112とを参照、もしくはセンサーデータ処理パターンと匂い要因情報格納部112及びセンサー配列情報格納部113の両方の情報とを参照することで、その作用アレイ部132のセンサーにおいて検出された表示パターンとにより、測定対象となる匂い要因の中の特定の匂いを検出し、識別することが可能となる。
1b.センサーアレイ
センサーの例としては、例えば、電気化学センサー、MOS電界効果トランジスターセンサー、金属酸化物半導体センサー、有機導電性ポリマーセンサー、水晶振動子センサー(QCMセンサー)、表面弾性波方式センサー、電荷結合素子センサー等があげられる。
これらのセンサーの中では例えば水晶振動子センサーが好適に用いられる。
本発明のQCM型センサーマルチアレイ200は、水晶基板220、振動部230、振動部表面に設けられた機能膜240、振動を励振電極250(図示せず)から構成されるQCM素子210を複数実装したものであって、異なる機能性膜240を有する一つ以上の複数のQCM素子210を共通基板200上に実装した、マルチアレイQCMセンサーである。
1c.QCM素子
水晶振動子すなわちQCM素子は、電極表面の重量変化を周波数変化として検出する質量センサーとなることは良く知られている。一般的に、図3にあるように、水晶基板320上の片面表面に電極ならびにガスまたは匂い分子などの吸着する機能膜340を配置し、反対側の表面には、励振電極350を配置する構成を有する。
従来から用いられている化学センサーには様々な種類があるが、特にQCMすなわち水晶振動子のような物理的振動検出素子に限っては、デバイスを小型化、つまり、厚みを薄くして電極面積も小さくすると、水晶振動子の共振周波数などが大きくなり、結果として周波数変化率が増えて検出限界がさがるという特性がある。これにより、低濃度の化学物質まで検出できるという特徴がある。
ここで、QCM素子(310)や励振電極(350)は任意の導電性材料で形成することができる。
各水晶振動子の共振周波数が同じ場合は、匂い吸着膜の厚みを変化させることで変化させていることも試みられている。加えて、異なる共振周波数の素子(例えば水晶基板の厚みを変えたオーバートーンモード等)を用いることもできる。
また、共通基板(300)は、インターポーザ基板など多層配線基板であり、水晶基板を励振動させるための励振電極(500)と実装配線、通電するための電極(301)が任意の位置に配置されており、電気的なグラウンドや他の電子回路基板等へ導通するため、例えば302にみられるようなバンプへ結線されている。
水晶振動子に厚さ分布を与えたコンベックス形状(レンズ形状または凸上)として、なお、片面を分離型の励振電極(振動用の電圧を入力する電極)にし、導電性膜は励振電極と反対面の対向する位置に設置する構造とすることができる。
同様に、振動エネルギーの封じ込め効果により、Q値およびコンダクタンスを向上することができ、小型化しても振動エネルギーが低下することなく、外部接触の干渉を受けにくい水晶振動子にすることができる。その結果、S/N比を向上させて高感度化される。
以上、本発明のセンサーアレイの構成について、一例として水晶振動子を用いたセンサーアレイについて説明したが、本発明がこれに限定されるものではないということは言うまでもない。
2.匂い識別方法
2a.匂い識別方法概要
図5は本発明の匂い識別方法の概要を示すフロー図である。
まず、図1に示される本発明の匂い識別システム100のサンプル情報取得部110を、測定対象となる匂い要因に接触させる(ステップ501)。この接触によりサンプル取得部111から匂い要因の分子が取り込まれ、センサーアレイ部112に送られる(ステップ502)。
これら相互作用データのパターンを測定される特定の匂い要因と関連付けされ、センサーアレイ上で反応しているセンサーの位置情報やその相互作用の強弱を含む情報としてセンサーデータ処理を行う(ステップ504)。
ここで、単一の匂い原因物質を検出したい場合には、センサー配列情報を参照しなくとも、匂い原因物質情報のみを参照、照合してその匂い原因物質を特定することも可能である。
2b.具体例
図6は、センサーアレイでの匂い原因物質の相互作用と配列情報を示す模式図である。
図7は、一例としてリンゴとコーヒーの香りを検出、識別するプロセスを示すシステム概念図である。
ここで、本発明のセンサーシステムに実装されている、異なる機能膜が塗布されたQCM素子群601はこれらリンゴもしくはコーヒーに含まれる複数の匂い原因物質に対して異なる相互作用を生じ、それぞれのQCM素子がそれぞれの反応に応じた周波数変化を出力する。
これらの構成(位置情報及び機能膜情報)及びセンサーの製品情報(製品情報(センサーの製造番号、アレイ位置情報(X、Y)、各QCM素子の種類、など)はあらかじめ図1に示すセンサー配列情報格納部132に格納しておく。
この、サンプルの臭気物質と各素子における相互作用とで発生する各素子の周波数変化をデジタルデータとして、センサーデータ処理部113に送り、そこでセンサーデータ処理を施すことで例えば画像データへと変換してセンサーアレイ情報を取得する(ステップ504)。
そして図7に図示するように、出力パターンがリンゴやコーヒーの匂いパターンと近似、もしくは該当すれば、ユーザーに対して、「匂いAはリンゴに似た匂いである」、「匂いBはコーヒーに似た匂いである」と結果を返す。
3.匂い識別装置
このセンサーユニットと、パターン識別ユニットとが、それぞれ図1に示すサンプル情報部110と総合システム部130とに対応しており、各ユニットは一つの装置内に設けても良いし、別個の装置として構成しても良い。これらの例については以下に例示する。
4.システムの利用例
本発明のシステムは、センサーアレイ部を小型化することが可能であるため、サンプル情報取得部をスマートフォン等の携帯デバイスに組み込むことも可能である。その場合は、情報処理部も当該デバイス内に組み込んでも良いし、該情報処理部についてはネットワーク通信手段を介してデバイス外に設けた情報処理部に必要な情報を参照にいく構成としても良い。
センサーアレイの組み込み位置は任意に設定可能であるが、図8では一例としてスマートフォン800のマイク設置部のダクト801の直下(ホームボタンの直下、マイク部品の直下)にセンサーアレイ部802を設けている。この構成では、例えば歯周病や内臓疾患による口腔内トラブルを検知可能なヘルスチェック機能を付与することが可能となる。
