  • Publication number: 20180014734
    Abstract: Tissue-mounted devices and methods for monitoring a thermal transport property (e.g., thermal conductivity, thermal diffusivity, heat capacity) of tissue, such as skin, are disclosed. The devices conformally mount to the tissue and comprise one or more thermal actuators and a plurality of sensors. The actuator applies heat to the tissue and the sensors detect a spatio temporal distribution of a physiological tissue parameter or physical property resulting from the heating. This spatio temporal information may be correlated with a rate, velocity and/or direction of blood flow, the presence of a vascular occlusion, circulation changes due to in flammation, hydration level and other physiological parameters.

  • Patent number: 7705280
    Abstract: The present invention provides plasmonic crystals comprising three-dimensional and quasi comprising three-dimensional distributions of metallic or semiconducting films, including multi-layered crystal structures comprising nanostructured films and film arrays. Plasmonic crystals of the present invention include precisely registered and deterministically selected nonplanar crystal geometries and spatial distributions providing highly coupled, localized plasmonic responses in thin film elements and/or nanostructures of the crystal. Coupling of plasmonic responses provided by three-dimensional and quasi-three dimensional plasmonic crystal geometries and structures of the present invention generates enhanced local plasmonic field distributions useful for detecting small changes in the composition of an external dielectric environment proximate to a sensing surface of the plasmonic crystal.
