Abstract: In one embodiment, a method is disclosed in which an analog sensor receives an electromagnetic (EM) wave (e.g., a radio frequency signal) from an interrogation device. The sensor converts a biological measurement of a subject into an electrical resistance and modulates a response to reflect the incident signal based on the electrical resistance. The sensor then provides the response to the interrogation device that corresponds to the biological measurement.

Abstract: A multilayer printed circuit as well as printed passive and active electronic components using additive printing technology is provided. The fabrication process includes a substrate and a first conductive layer that is printed with conductive ink on the substrate. An insulation layer that has uniform thickness is printed on the first conductive layer and the substrate, less via cavities, test point cavities, and a surface mount component contact point and mounting cavities. The insulation layer is replaceable with resistive layer or semi-conductive layer to fabricate electronic components. The vias are printed with conductive ink inside of the via cavities. Additionally, a second conductive layer is printed on the vias and over the insulation layer. The insulation, resistive, or semi-conducting layer, the vias, and the conductive layers are repeatedly printed in sequence to thus form the multilayer printed circuit.
