摘要： An example device includes a fluid lens, where the fluid lens includes a membrane, a substrate, and a fluid located within an enclosure formed at least in part by the membrane and the substrate. The membrane may be an elastic membrane. The fluid may include an amount of an additive that is effective to appreciably reduce bubble formation within the fluid, such as when a negative pressure is applied to the fluid. In some examples, the additive may include particles, such as nanoparticles. The additive may include a thixotropic agent that helps to impart an appreciable thixotropic property to the fluid. Various other methods, systems, and computer-readable media are also disclosed.

摘要： A liquid lens architecture includes a transparent substrate, a multilayer thermoplastic polyurethane (TPU)-based membrane overlying at least a portion of the transparent substrate, and a liquid layer disposed between and abutting the transparent substrate and the multilayer thermoplastic polyurethane-based membrane. The TPU-based membrane may exhibit a reversible elastic response to imposed strains of up to approximately 2% and is configured to limit the transpiration of fluid to less than approximately 10−2 g/m2/day.

摘要： Disclosed devices may include a fluid lens that includes a membrane, optionally a substrate, and a fluid located within an enclosure that may be at least partially defined by the substrate and the membrane. A coating may be disposed on at least a portion of the interior surface of the enclosure. The coating may have a coating surface in contact with the fluid. The coating may significantly reduce bubble formation within the fluid (e.g., compared with an uncoated surface). Example devices include adjustable fluid lenses that may be adjusted to a plano-concave configuration. Various other methods, systems, and computer-readable media are also disclosed.
