Abstract: A drug delivery system includes a substrate, an integrated sensor disposed on the substrate, a drug delivery element disposed on the substrate, and a control unit coupled to the integrated sensor and the drug delivery element. The integrated sensor includes first and second electrodes disposed on a first surface of the substrate. The drug delivery element includes a reservoir disposed on the first surface of the substrate, a thermally active polymer enclosing the reservoir, and a heating coil disposed over the thermally active polymer. The control unit is configured to measure a biological parameter by measuring a voltage difference between the first and second electrodes of the integrated sensor, and to apply a trigger signal to the heating coil of the drug delivery element responsive to the measured biological parameter indicating a designated condition to heat up the thermally active polymer to selectively release a drug from the reservoir.

Abstract: A computer-implemented method and thermal imaging device includes a layer of plasmonic material and a processor. The layer of plasmonic material receive electromagnetic radiation from an object and generates radiance measurements of the electromagnetic radiation at a plurality of wavelengths. The processor determines an emissivity and temperature of the object from the radiance measurements and forms a thermal-based electronic image of the object from the determined emissivity and temperature.
