摘要： 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.

摘要： An electrochemical device includes an electrochemical cell and an electric circuit. The electrochemical cell comprises a first solid component and a second solid component. The two solid components comprise same chemical elements but have different concentrations of at least one type of the chemical elements. A solid electrolyte is arranged between the two solid components. The solid electrolyte is a dielectric material. The electric circuit is connected to the electrochemical cell. The electrochemical cell may be operated according to a redox process, so as to exchange chemical elements of the at least one type between the first solid component and the second solid component and thereby change an electrical conductance of each of the two solid components.

摘要： A sensor apparatus comprising a portable sensor body. The sensor body includes a support with one or more sensing electrodes, and electric connections connecting to the electrodes. The apparatus further includes a storage container, designed to receive at least a part of the support that includes one or more of the electrodes, for storing the sensor body. The container comprises a deformable wiper. The wiper is shaped correspondingly with the support and electrodes thereof, to wipe liquid (and/or other materials contained therein) off the support responsive to inserting the latter in the container and, conversely, responsive to de-inserting the support from the container. Mutually corresponding parts of the sensor body and the container may form a fastener, so as to be able to create a non-permanent joint between the sensor body and the container responsive to the sensor body being fully inserted in the container.
