摘要：

Variable-focus cylindrical liquid/liquid microlenses and spherical liquid microlens arrays formed using liquid/liquid interfaces are actuated by thermoresponsive hydrogels (see figure). The shapes of the microlenses are realized by patterning apertures with corresponding shapes. Hydrogels located within microfluidic channels regulate the focal lengths of the microlenses by expanding and contracting, in response to changes in the environmental temperature.
