    摘要： Analyte sensors and methods for fabricating analyte sensors are provided. In an exemplary embodiment, a method for fabricating a planar flexible analyte sensor includes sputtering platinum onto a polyester base layer to form a layer of platinum. The method includes patterning the layer of platinum to form working electrodes and additional electrodes. Further, the method includes forming an insulating dielectric layer over the base layer, wherein the insulating dielectric layer is formed with openings exposing portions of the working electrodes and portions of the additional electrodes. Also, the method includes partially singulating individual sensors from the base layer, wherein each individual sensor is connected to the base layer by a tab. The method further includes depositing an enzyme layer over the exposed portions of the working electrodes and coating the working electrodes with a glucose limiting membrane.

    摘要： A combination electrode includes a working electrode, a reference electrode, a hydrogel diaphragm, an outer tube and an inner tube. The working electrode is disposed in the inner tube. The reference electrode is disposed in a reference chamber formed between the inner tube and the outer tube. The hydrogel diaphragm seals the opening between an end of the outer tube and the inner tube when the hydrogel swells upon coming in contact with a first electrically conductive fluid that is introduced into the reference chamber. The diaphragm is coupled to the reference electrode in an electrically conductive manner through the first electrically conductive fluid, which contacts both the reference electrode and the diaphragm. The inner tube is closed by a glass membrane that is coupled to the working electrode in an electrically conductive manner through a second electrically conductive fluid that contacts both the glass membrane and the working electrode.

    摘要： A system includes a circuit configured to detect a voltage corresponding to an electrical measurement of a nanopore. The system also includes a component configured to compare the voltage to another voltage. Based at least in part on the comparison, a one bit indicator is determined. The one bit indicator indicates whether the voltage indicates a change in a state of the nanopore. In the event it is determined that the voltage indicates the change in the state of the nanopore, a multiple bit signal is provided for output.

    摘要： Various example embodiments described herein relate to an electrochemical gas sensor. The electrochemical gas sensor can include a sensor cap having one or more solid features disposed on a surface of the sensor cap. The electrochemical gas sensor can include a counter electrode configured to generate a gas during use of the electrochemical gas sensor. The electrochemical gas sensor can include a vent assembly adapted to release at least a portion of the gas generated at the counter electrode out from the electrochemical gas sensor. The vent assembly can include a vent conduit and a vent membrane that defines a passage for the gas to flow from an extended portion of the counter electrode, to the vent conduit, via the vent membrane, so as to be vented from the electrochemical gas sensor.
