Abstract
省エネルギーで駆動できる小型のマイクロミラーデバイスを提供すること。
【解決手段】
表面(22)を有する基板(20)と、基板表面から離して基板表面に対して実質的に平行な向きに配置されたプレートとを備え、プレートと基板表面との間に空洞を画定するように構成されたマイクロミラーデバイス。マイクロミラーデバイスに電気信号を加えたときに動きを有する誘電泳動マイクロエマルジョンを空洞内に配置し、基板表面とプレートとの間に反射素子(42)を配置して、反射素子が、第1の位置と少なくとも1つの第2の位置との間で動かされるようにする。誘電泳動マイクロエマルジョンは連続的な油相を有する。

Description
本特許出願は、2002年4月30日に出願された「Micro-Mirror Device」と題する米国特許出願第10/136,719号、2003年3月12日に出願された「Micro-Mirror Device Including Dielectrophoretic Liquid」と題する米国特許出願第10/387,245号、及び2003年3月12日に出願された「Micro-Mirror Device Including Dielectrophoretic Liquid」と題する米国特許出願第10/387,312号に関連する。
一実施形態において、いくつかのマイクロエマルジョンについて、そのマイクロミラーデバイスのミラーの動きを助ける能力を検査した。表1から明らかなように、サンプルA、B、CおよびEは、マイクロミラーデバイスのミラーを動かした。陰イオン界面活性剤および5パーセントの水を含むサンプルAは、勢いは悪いが、ミラーを動かした。しかしながら、陰イオン界面活性剤および約5パーセントよりも多くの水を含むサンプルDおよびFは、マイクロミラーデバイスのミラーを実質的に動かさなかった。
