Abstract
A sensor device, such as a biosensor, may comprise a polymer substrate, which is structured so as to form sets of microneedles and respective vias. The microneedles extend, each, from a base surface of the substrate. Each of the vias extends through a thickness of the substrate, thereby forming a corresponding set of apertures on the base surface. Each of the apertures is adjacent to a respective one of the microneedles. The device further may comprise two or more electrodes, these including a sensing electrode and a reference electrode. Each electrode may comprise an electrically conductive material layer that coats a region of the substrate, so as to coat at least some of the microneedles and neighboring portions of said base surface. Related devices, apparatuses, and methods of fabrication and use of such devices may be provided.
