Abstract: A polarizer is formed with an arrangement of polymer fibers substantially parallel within a polymer matrix. The polymer fibers are formed of at least first and second polymer materials. At least one of the polymer matrix and the first and second polymer materials is birefringent, and provides a birefringent interface with the adjacent material. Light is reflected and/or scattered at the birefringent interfaces with sensitivity to the polarization of the light. In some embodiments, the polymer fibers are formed as composite fibers, having a plurality of scattering polymer fibers disposed within a filler to form the composite fiber. In other embodiments, the polymer fiber is a multilayered polymer fiber. The polymer fibers may be arranged within the polymer matrix as part of a fiber weave.

Abstract: Microneedle arrays, methods of manufacturing microneedles and methods of using microneedle anays. The microneedles (20) in the microneedle arrays may be in the form of tapered structures that include at least one channel (22) formed in the outside surface of each microneedle. The microneedles may have bases (26) that are elongated in one direction. The channels in microneedles with elongated bases may extend from on of the ends of the elongated bases towards the tips of the microneedles. The channels formed along the sides of the microneedles may optionally be terminated short of the tips of the microneedles The microneedle arrays may also include conduit structures formed on the surface of the substrate on which the microneedle array is located. The channels in the microneedles may be in fluid communication with the conduit structures. One manner of using microneedle arrays of the present invention is in methods involving the penetration of skin to deliver medicaments or other substances and/or extract blood or tissue.

Abstract: Microneedle devices and methods of manufacturing the microneedle devices. The microneedle devices include microneedles protruding from a substrate, with the microneedles piercing a cover placed over the substrate surface from which the microneedles protrude. The cover and the microneedle substrate together define a capillary volume in fluid communication with the base of each microneedle. One manner of using microneedle arrays of the present invention is in methods involving the penetration of skin to deliver medicaments or other substances and/or extract blood or tissue. Manufacturing methods may include simultaneous application of pressure and ultrasonic energy when piercing the cover with the microneedles.

Abstract: Una fibra de polimero compuesto comprende un material de relleno de polimero y una pluralidad de fibras de dispersion de polimero dispuestas dentro del material de relleno. Al menos uno de los materiales de relleno y las fibras de dispersion se forma de un material birrefringente. Los indices de refraccion del material de relleno y las fibras de dispersion pueden compararse sustancialmente para la luz incidente en un primer estado de polarizacion sobre la fibra de polimero compuesto y mal comparado para la luz incidente en el estado de polarizacion ortogonal. Las fibras de dispersion pueden disponerse para formar un cristal fotonico dentro de la fibra compuesta. Las fibras compuestas pueden extrudirse y pueden formarse en hilados, o tejido o los similares. Si el material de relleno es soluble, puede lavarse sacandose del hilado o tejido, y las fibras de dispersion despues pueden infiltrarse con una resina que se cura sustancialmente.

Abstract: Methods of fabricating optical elements that are encapsulated in monolithic matrices. The present invention is based, at least in one aspect, upon the concept of using multiphoton, multi-step photocuring to fabricate encapsulated optical element(s) within a body of a photopolymerizable composition. Imagewise, multiphoton polymerization techniques are used to form the optical element. The body surrounding the optical element is also photohardened by blanket irradiation and/or thermal curing to help form an encapsulating structure. In addition, the composition also incorporates one or more other, non-diffusing binder components that may be thermosetting or thermoplastic. The end result is an encapsulated structure with good hardness, durability, dimensional stability, resilience, and toughness.
