Abstract: An example device may include a light source, an optical element, and, optionally, an encapsulant layer. A light beam generated by the light source may be received by the optical element and redirected towards an illumination target, such as an eye of a user. The optical element may include a material, for example, with a refractive index of at least approximately 2 at a wavelength of the light beam. The light source may be a semiconductor light source, such as a light-emitting diode or a laser. The optical element may be supported by an emissive surface of the light source. Refraction at an exit surface of the optical element, and/or within a metamaterial layer, may advantageously modify the beam properties, for example, in relation to illuminating a target. In some examples, the light source and optical element may be integrated into a monolithic light source module.

Abstract: A liquid lens fluid composition includes a polyphenyl ether molecule having from 2 to 7 aromatic rings, where the rings include ortho substitutions, meta substitutions, or a combination of ortho, meta, and para substitutions. Inter-ring linkages may include sulfur or oxygen. The liquid lens fluid composition may be characterized by a refractive index over the visible spectrum of at least 1.4, a viscosity at room temperature of less than approximately 1000 cP, and a freezing point of less than approximately −10° C.

Abstract: A thin film assembly includes an optical thin film and a discontinuous spacer layer disposed over a major surface of the optical thin film. Within a multilayer stack of optical thin films, the spacer layer may be located between opposing regions of adjacent thin films such that the spacer layer separates the adjacent thin films and inhibits or prevents surface-to-surface contact.

IPC: C08J5/18
Abstract: A mechanically and piezoelectrically anisotropic polymer thin film is formed from a crystallizable polymer and an additive configured to interact with the polymer to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film and its method of manufacture may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 5% of the molecular weight of the crystallizable polymer. Example polymers may include vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, and vinyl fluoride. Example additives may occupy up to approximately 60 wt. % of the polymer thin film. The polymer thin film may be characterized by a piezoelectric coefficient (d31) of at least approximately 5 pC/N or an electromechanical coupling factor (k31) of at least approximately 0.1.

Abstract: A method of forming a uniaxially oriented crystalline polymer article includes heating a segment of a crystallizable polymer article to a first temperature, applying a stress to the crystallizable polymer article in an amount effective to induce a positive strain within the segment of the crystallizable polymer article, and heating the segment of the crystallizable polymer article to a second temperature greater than the first temperature while continuing to apply the stress.

Abstract: A liquid lens includes a transparent substrate, a multilayer polyurethane-based membrane overlying the transparent substrate, and a liquid layer disposed between and abutting the transparent substrate and the multilayer polyurethane-based membrane. The multilayer polyurethane-based membrane, which may include thermoplastic and/or thermoset polymer layers, may be formed by slot die coating or gravure coating one or more constituent layers and may exhibit a reversible elastic response to imposed strains of up to approximately 5% while limiting the transpiration of fluid therethrough to less than approximately 10−2 g/m2/day.

Abstract: An example apparatus may include a display and an optical configuration configured to provide an image of a display, for example, in a head-mounted device. The optical configuration may include a Fresnel lens assembly including a Fresnel lens and a reflective polarizer. The Fresnel lens may have a structured surface including a plurality of facets, and there may be a step between pairs of neighboring facets. The reflective polarizer may include a plurality of reflective polarizer portions, where each reflective polarizer portion conforms to a corresponding facet of the Fresnel lens. The reflective polarizer may be configured to reflect a first polarization and transmit a second polarization of incident light. The optical configuration may form an image of the display viewable by a user when the user wears the apparatus. Other devices, methods, systems, and computer-readable media are also disclosed.

Abstract: Mechanically and piezoelectrically anisotropic polymer fibers may be formed by spinning a polymer solution or gel that includes a high molecular weight crystallizable polymer and a liquid solvent. The solvent may be configured to interact with the polymer to facilitate chain alignment and, in some examples, create a higher crystalline content within the spun fibers. The polymer solution may also include a low molecular weight additive. The high and low molecular weight polymers may each be characterized by a bimodal molecular weight distribution where the molecular weight of the additive is less than the molecular weight of the crystallizable polymer. The polymer(s) and the additive(s) may be independently selected from vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropene, vinyl fluoride, etc. The spun fibers may be oriented, annealed, poled, and woven or laminated to form a polymer thin film having a high elastic modulus and a high electromechanical coupling factor.
