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.

Abstract: Aspects of the present disclosure are directed to a pH control device. The device comprises a substrate, on which is defined a flow path adapted to receive a liquid. The device further comprises a set of electrodes, which includes a pH sensing electrode and pH generation electrodes. The electrodes are arranged along the flow path. The pH sensing electrode is arranged so as to be subjected to a change in pH of a portion of the liquid on the flow path, as caused by the pH generation electrodes. In addition, the device includes a controller, which is configured to apply a voltage across the pH generation electrodes, based on a signal obtained via the pH sensing electrode and a reference electrode. This enables local control a pH of the liquid portion. The device may further be embodied as a sensor, additionally comprising a detection electrode.

Abstract: A sensor comprises a microfabricated chip having a surface with one or more cavities formed thereon, the cavities including sensing components, one or more lids, each covering said surface so as to close at least one of said cavities, the lids contacting rims that delimit said cavities on said surface. Electric circuit portions join, each, a respective one of the lids, to allow the lids to be partly dissolved, electrochemically, responsive to being exposed to an electrochemical solution. In addition, masking material portions cover peripheral regions of the lids at the level of the rims, so as to seal the lids and shield such peripheral regions from said electrochemical solution, in operation. Related apparatuses and sensing methods may be provided.

Abstract: One or more embodiments of the present invention are directed to a photovoltaic system. The system comprises photovoltaic cells, arranged side-by-side to form an array of photovoltaic cells. It further involves a cooling device, which comprises one or more layers, wherein the layers extend opposite to the array of photovoltaic cells and in thermal communication therewith, for cooling the cells, in operation. The one or more layers are structured such that a thermal resistance of the photovoltaic system varies across the array of photovoltaic cells, so as to remove heat from photovoltaic cells of the array with different heat removal rates, in operation. One or more embodiments of the present invention are further directed to related systems and methods for cooling such photovoltaic systems.
