    Abstract: Methods, systems, and devices are disclosed for fabricating 3D piezoelectric materials. In one aspect, a method includes photopolymerizing a selected portion of a two dimensional plane in a sample of a photolabile polymer solution containing piezoelectric nanoparticles to form a layer of a piezoelectric material, the photopolymerizing including directing light from a light source based on a pattern design in the selected portion of the photolabile polymer solution; and moving one or both of the sample and the directed light to photopolymerize another selected portion of another two dimensional plane in the sample to form another layer of the piezoelectric material.

    Abstract: The document discloses transferrable hyperbolic metamaterial particles (THMMP) that display broadband, selective, omnidirectional absorption and can be transferred to secondary substrates, allowing enhanced flexibility and selective transmission. A device having metamaterial nanostructures includes a substrate and metamaterial nanostructures engaged to the substrate to form an optical layer to interact with light incident to the optical layer to exhibit optical reflection or absorption or transmission that is substantially uniform over a spectral range of different optical wavelengths associated with materials and structural features of the metamaterial nanostructures, each metamaterial nanostructure including different material layers that are interleaved to form a multi-layer nanostructure.

    Abstract: Methods, structures, devices and systems are disclosed for implementing a fiber optic force sensing transducer. In one aspect, an exemplary fiber optic force sensing transducer device includes an optical fiber coated by at least one layer of a polyelectrolyte material that utilizes the movement of optical structures coupled to the external polyelectrolyte layer in an evanescent field produced by the optical fiber to detect forces imposing on the fiber. In one aspect, an optical sensing device includes an optical waveguide that internally guides light, one or more layers formed outside the optical waveguide within an evanescent field of the guided light in the optical waveguide, and one or more optical structures coupled to the one or more layers in the evanescent field to emit light based on interaction with the evanescent field to indicate a position of an optical structure relative to an external surface of the optical waveguide.
