摘要： A method is provided for color tuning a plasmonic device with a color tunable electronic skin. A plasmonic electronic skin is used, including a first substrate, a plasmonic structure, an electrically conductive transparent first electrode layer, an electrically conductive transparent second electrode layer, and a polymer-networked liquid crystal (PNLC) layer interposed between the first and second transparent electrode layers. In response to receiving a color tuning voltage, a full visible spectrum incident light, and a PNLC switch voltage, the plasmonic structure generates a first primary color. A primary color exhibits a single wavelength peak with a spectral full width at half magnitudes (FWHMs) in the visible spectrum of light. In response to receiving the PNLC switch voltage between the first and second electrode layers, the PNLC layer passes incident light.

摘要： An electrical pressure sensor is provided with a method for measuring pressure applied to a sensor surface. The method provides an electrical pressure sensor including a sealed chamber with a top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium. When the top surface of the sensor is deformed in response to an applied pressure, the elastic polymer medium is compressed. In response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance between metallic nanoparticles, the electrical resistance is decreased between the first and second electrodes through the elastic polymer medium.

摘要： A display device is provided for reflecting a black color, as enabled by an optical splitting photonic liquid crystal waveguide. Sets of top and bottom electrodes are formed in a periodic pattern. A first dielectric layer overlies the set of bottom electrodes, made from a liquid crystal (LC) material with molecules having dipoles responsive to an electric field. A plasmonic layer, including a plurality of discrete plasmonic particles, is interposed between the sets of top and bottom electrodes, and is in contact with the first dielectric layer. A voltage potential is applied between the top and bottom electrodes, generating an electric field. Dipole local orientation and non-orientation regions are created in the liquid crystal molecules in response to the electric field, and a wavelength of light outside the visible spectrum is reflected in response to optical spectrum splitting of the incident light.

摘要： An electrical pressure-sensitive reflective display includes an array of display pixels, each with a transparent top surface, first electrode, second electrode, an elastic polymer medium, and metallic nanoparticles distributed in the elastic polymer medium. When a first voltage potential is applied between the first and second electrodes of each display pixel, a first color is reflected from the incident spectrum of light, assuming no pressure is applied on the top surface of each display pixel. When the top surface of a first display pixel is deformed in response to an applied pressure, the elastic polymer medium in the first display pixel is compressed, decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance in the first display pixel. In response to decreasing the metallic nanoparticle-to-metallic nanoparticle mean distance, the color reflected from the incident spectrum of light by the second display pixel is changed from the first color to second color.
