Abstract
【解決手段】基板に切り込まれて前記基板に狭幅領域(412)を形成するノッチを有する基板(402)と、一つ又はそれ以上の導電層から形成された少なくとも一つのセンサ電極(404)と、を含む人体内埋め込み用センサ(400)及びその製造方法。好ましくは、前記基板(402)の厚さが約25μmから350ミクロンmの範囲にあるが、前記基板の幅は5μmから750μmの範囲であることができる。前記センサは、スロット(410)を有するスロット付き針(408)を含むセンサアセンブリ内に組み込まれてもよい。前記狭幅領域(412)を生成する前記ノッチ(406)により、前記基板(402)が前記スロット付き針の中にスライドすることが可能になり、このスロット付き針は、前記狭幅領域の通過を可能にするほど十分に狭いスロットを有する。しかし、前記基板の非狭幅領域(414)は、前記スロット付き針(408)が前記スロット(410)を通って引き出されることを妨げる。前記スロット付き針(408)の前記スロット(410)はまた、前記基板(402)の前記狭幅領域(412)が前記スロットをすべりおりることを可能にしてもよい。
