Abstract: A polymer multilayer includes two or more laminated layers of ultra-drawn, ultra-high molecular weight polyethylene or high density polyethylene. A transparent laminated structure may include such a polymer multilayer disposed between a pair of transparent substrates. The polymer multilayer may be configured to induce a compressive stress in a near surface region of each transparent substrate, which may improve the toughness and fracture resistance of the laminated structure. A photothermal dye may be incorporated into the polymer matrix and the compressive stresses may be achieved using photothermal actuation of the dye-containing polyethylene layers.

Abstract: 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.

Abstract: A method of forming a low reflectivity coating on an optical surface for wide angle of incidence is provided. The method includes depositing a low refractive index layer of material on a stack of dielectric layers, depositing a hydrophobic compatible material on the stack of dielectric layers, forming a blend interface layer on the stack of dielectric layers, the blend interface layer including a portion of the low refractive index layer of material and a portion of the hydrophobic compatible material, and depositing a hydrophobic layer of material adjacent to the blend interface layer.

Abstract: A device includes a light source to emit light and a light detector to receive the light emitted by the light source. The device may include a high voltage optical transformer and may be configured such that the light detector is laterally spaced away from the light source. In some architectures, the light source and the light detector may be arranged in a common plane. A photonic integrated circuit may be used to couple light emitted from the light source to the light detector.

Abstract: A solar reflective coating includes a reflective layer and a black layer overlying the reflective layer, where the black layer includes active particles dispersed throughout a matrix. Example active particles include phosphor microcrystals adapted to reflect incident non-visible radiation and convert incident visible radiation to non-visible radiation.

Abstract: An electromechanical actuator includes a primary electrode, a secondary electrode overlying at least a portion of the primary electrode, and an electroactive layer disposed between the primary electrode and the secondary electrode, where the electroactive layer has a first curvature when zero voltage is applied between the primary electrode and the secondary electrode, and a second curvature when a non-zero voltage is applied between the primary electrode and the secondary electrode.

Abstract: A method includes applying a stress to a polymer thin film to stretch the polymer thin film along a first in-plane direction, and subsequently applying a stress to the polymer thin film to stretch the polymer thin film along a second in-plane direction orthogonal to the first in-plane direction to form an ultra-high modulus polymer thin film. Calendaring or hot pressing of the ultra-high modulus polymer thin film may improve its optical and/or thermal properties.

Abstract: A high voltage-driven system includes a high voltage optical transformer and a high voltage driven device, where the high voltage optical transformer is located in close proximity to the high voltage driven device. A high voltage connection between the high voltage optical transformer and the high voltage driven device may be shorter than a low voltage connection between the high voltage optical transformer and a low voltage power source used to control the transformer.

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.
