Abstract
Examples include a device including a fluid lens having a membrane, a substrate, and a fluid at least partially enclosed between the membrane and the substrate. One or more support structures may be configured to provide a guide path for an edge portion of the membrane, which may be an elastic membrane in tension. In some examples, a membrane includes a membrane polymer, such as a thermoplastic urethane polymer, and a polymer additive, such as an acrylate polymer. The polymer additive may reduce or substantially eliminate diffusion of the fluid into the membrane, which may increase the stability and performance of the fluid lens.
