Abstract: A vertically integrated multispectral imaging sensor includes a first metal contact layer on a substrate, an SiO2 layer on the first metal contact layer with a first detector element embedded in a hole therein, a first graphene layer that covers the first detector element, a second metal contact layer on the SiO2 layer on one side of the first graphene, an AlO3 layer on the SiO2 layer, in which a second detector element is embedded in a hole over the first graphene layer, a second graphene layer on the second detector element, and a third metal contact layer on the AlO3 layer adjacent to the second graphene layer. The first detector material is sensitive to a different wavelength band of the electromagnetic spectrum than the second detector material.

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 three-dimensional integration of synapse circuitry is formed. One or more neuron layers each comprises a plurality of computing elements, and one or more synapse layers each comprising an array of memory elements are formed on top of the one or more neuron layers. A plurality of staggered through-silicon vias (TSVs) connect the one or more neuron layers to the one or more synapse layers and operate as communication links between one or more computing elements in the one or more neuron layers and one or more memory elements in the one or more synapse layers.
