    Abstract: An apparatus (400) comprises a first conductive substrate (408) (e.g., a metal foil) having a first surface; a plurality of conductive stalks (404) (e.g., carbon nano-tubes) extending from the first surface; an electrically insulating coating (406) (e.g., sulfur) about the carbon stalks; a second conductive substrate (420) (e.g., a lithium oxide foil); and an electrolyte (430) (e.g., a polymer electrolyte) disposed between the first surface of the first conductive substrate (408) and the second conductive substrate (420). In various embodiments: the sulfur is disposed at a thickness of about 3 nanometers +1 - 1 nanometer; the stalks (404) are at a density such that a gap between them is between 2 and 200 diameters of an ion transported through the electrolyte (430); and there is a separator layer (432) within the electrolyte (430) having a porosity amenable to passage by such ions. Also detailed is a method for making the foil with the coated carbon nano-tubes.

    Abstract: An apparatus comprises first 201 and second 202 electrodes separated by an electrolyte 203, the first and second electrodes are configured to exhibit a potential difference therebetween on interaction of the first electrode with an analyte. The first electrode is configured such that its electrical conductance and electrochemical potential are dependent upon the amount of analyte present, the electrical conductance and electrochemical potential of the first electrode affecting the potential difference between the first and second electrodes. The apparatus further comprises respective first 204 and second 205 terminals configured for electrical connection to a readout circuit to enable determination of the presence and/or amount of analyte based on the potential difference. The first electrode may be a composite of graphene oxide and a conducting polymer and the analyte may be a chemical or biological species. The analyte may be water and the apparatus a humidity sensor.
