    Abstract: A microelectromechanical (MEMS) device (10) is provided that includes a microelectronic substrate (50) and a thermally actuated microactuator (20). For example, the MEMS device (10) may be a valve. As such, the valve may include at least one valve plate (30) that is controllably brought into engagement with at least one valve opening (40) in the microelectronic substrate (50) by selective actuation of the microactuator (20). While the MEMS device (10) can include various microactuators (20), the microactuator advantageously includes a pair of spaced apart supports (22) disposed on the substrate (50) and at least one arched beam (24) extending therebetween. The microactuator (20) may further include metallization traces (70) on distal portions (23) of the arched beams (24) to constrain the thermally actuated regions of arched beams to medial portions thereof. The valve may also include a latch (680) for maintaining the valve plate (30) in a desired position without requiring continuous energy input to the microactuator (20).

    Abstract: 簡單的說,依據本發明的一具體例,一開關結構或是例如一閥件,馬達或光學開關之類似物,可以用一熱反應性聚合物為基礎來架構。在一第一溫度下熱反應性聚合物可以處於一第一體積狀態中,而在一第二溫度下熱反應性聚合物可以處於一第二體積狀態中。在熱反應性聚合物的體積上的變化可以被用來推動或拉引開關、閥件、電動機、光學開關,等等,以使得該結構運作。
