精密工程已被用于宏观世界和微观尺度仅与刚性材料。通常用于微流体和其他生物MEMS应用的软柔性材料尚未与弹性平均对准。我们报告使用互补的凸起和凹陷的圆形特征来对准聚合物层，并证明对准精度和可重复性。对准是在皮氏培养皿中完成的，在微模塑弹性体聚合物片的两个表面之间具有液体薄层。这些层通过简单的手眼操作对齐。我们测试不同直径的圆形几何形状，在1-3 μ m的范围内获得精确度和重复性值，通过硅母模成型的薄聚合物片。这是对现有手动、移动载物台和自对准技术的重大改进，也是为复杂的3-D聚合物结构铺平道路的新概念证明。[2008-0093]
Precision engineering has been used in the macro-world and in the microscale only with rigid materials. Soft flexible materials commonly used for microfluidics and other bio-MEMS applications have not been aligned with elastic averaging. We report the use of complementary raised and recessed circular features to align polymer layers and demonstrate alignment accuracy and repeatability. The alignment is accomplished in a Petri dish with a thin layer of liquid between the two surfaces of micromolded elastomeric polymer sheets. The layers are aligned with simple hand-eye manipulation. We test circular geometries of varying diameters, obtaining accuracy and repeatability values in the range of 1-3 mu m across thin polymer sheets molded from silicon masters. This is a significant improvement over existing manual, moving stage, and self-alignment techniques and a novel proof of concept that paves the way for complex 3-D polymer constructs. [2008-0093]
