Abstract
【解決手段】生体(150)の表面(155)を貫いて物質を輸送する無針式経皮輸送装置(100)は、物質を貯蔵するリザーバ(113)、リザーバに連通しているノズル(114)、およびリザーバに連結している制御可能な電磁アクチュエータ(125)を備えている。アクチュエータは、ローレンツ力アクチュエータと称され、固定の磁石アセンブリ(105)および可動コイルアセンブリ(104)を備えている。コイルアセンブリは、端部がリザーバ内に位置するピストン(126)を駆動する。アクチュエータは、電気入力を受け取り、これに応答してピストンに作用する対応する力を発生し、リザーバと生体との間の物質の無針式輸送を行う。
