Experimental setup and results of the focal length characterization. (a) Illustration of the focal length variation with electric field, (b) experimental setup for the focal length measurement and an image (inset) of the fabricated micro-lens, (c) measured variable focal lengths versus applied electric field, (d) schematic of the electric field-dependent imaging experiment, and (e) captured images of a test object; a video clip of this test is available as Supplementary Movie S1.
