Abstract: An optically anisotropic polymer thin film includes a crystallizable polymer and an additive configured to interact with the polymer (e.g., via π-π interactions) to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 50% of the molecular weight of the crystallizable polymer. Example crystallizable polymers include polyethylene naphthalate, polyethylene terephthalate, polybutylene naphthalate, polybutylene terephthalate, as well as derivatives thereof. Example additives, which may occupy up to approximately 10 wt. % of the polymer thin film, include aromatic ester oligomers, aromatic amide oligomers, and polycyclic aromatic hydrocarbons, for example. The optically anisotropic polymer thin film may be characterized by a refractive index greater than approximately 1.7 and an in-plane birefringence greater than approximately 0.2.

Abstract: A fluidic optical element includes a fluid bilayer having a first fluid layer and a second fluid layer defining a fluid interface therebetween, and an electrode disposed over a surface of the fluid bilayer. The geometry of the fluid interface and hence the optical response of the fluid bilayer to incident light may be manipulated using the principle of dielectrophoresis.

Abstract: Disclosed apparatus may include a membrane, a first electrode supported by the membrane, a second electrode, and optionally a controller configured to control an electrical potential applied between the first electrode and the second electrode. Example apparatus may include one or more flexible membranes that may, at least in part, define an enclosure that is at least partially filled with a dielectric fluid. A flexible membrane may include a functionalized polymer or inorganic dielectric material, such as a fluoropolymer composite including at least one electrically conductive additive and/or at least one toughener. Examples also include associated materials (e.g., polymers), methods of fabrication, methods of apparatus operation, and systems.

Abstract: Systems and methods of controlling activation of different input elements using an actuator are disclosed herein. An example method includes in response to determining that a representation of a user's finger is located within a predefined distance of an input element: obtaining information regarding an amount of force needed to actuate the input element, and causing adjustment of a physical characteristic of an actuator while the actuator is associated with the input element. The method further includes, in response to an input having at least the amount of force applied by the user's finger to a component of the actuator while the actuator is associated with the input element, causing an input command to be performed and providing a haptic response via the actuator component.

Abstract: Systems and methods of controlling activation of different input elements using an actuator are disclosed herein. An example method includes in response to detecting that a representation of a finger is located by a first input element: obtaining information regarding a first amount of force to actuate the first input element, and causing adjustment of a physical characteristic of an actuator so that a first amount of force directed to a component of the actuator activates the first input element. In response to detecting that the representation of the finger is located by a second input element, the method also includes: obtaining information regarding a second amount of force distinct from the first amount of force, and causing adjustment of the physical characteristic of the actuator so that the second amount of force directed to the component of the actuator activates the second input element.
