Abstract: A variable-focus lens system that includes a lens assembly having an electrowetting liquid lens that can be wrapped onto a curved surface such as a lens without distorting a chamber holding the electrowetting liquid lens is provided. The lens assembly includes a container body having a cup, in which the chamber is defined, and supports that extend in different directions from the cup. A flexible base substrate is arranged under the container body. Both the container body and flexible base substrate may be made from a soft polymer material and made using low-temperature fabrication processes. The flexible base substrate may be thinner than the container body and provide a relatively large surface area that engages the curved surface such that the stresses associated with wrapping a micro lens assembly onto the curved surface may be primarily absorbed by the flexible base substrate.
