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.

摘要： Described is a basic device for analysing a biological fluid comprising at least one pair of electrodes (2) and a source of electricity (3) acting in conjunction to form an electrochemical cell to which the biological fluid is conveyed by means of a micro-fluid circuit (5). A functionalized coating is applied to the pair of electrodes (2) for receiving and retaining at least one marker of the biological fluid. The device also comprises a sensor (4) configured to measure a current signal in the electrochemical cell and a transmission module (6) with which it can be transmitted. Several basic measuring devices can be combined together to make a more complex system for use, for example, in hospitals or for testing laboratories which is able to perform many measurements in parallel providing multiple responses in the shortest possible time.

摘要： A gas detection apparatus and method for measuring humidity using an electrochemical gas sensor. The gas detection apparatus comprises an electrolyte-based electrochemical gas sensor and a controller configured to measure the average humidity value within an ambient environment over a period of time. The average ambient humidity value over the period of time is determined based on the average rate of change over the period of time of the electrolyte concentration within the electrolyte gas sensor of the gas detection apparatus over the period and the average temperature in the ambient environment over the period of time. The gas sensing apparatus may be configured to communicate the average ambient humidity value within the ambient environment to a second electrochemical gas sensor or a second gas detection apparatus within the same ambient environment.

摘要： A microfabricated electrochemical gas sensor is disclosed. The sensor includes electrodes produced from conductor layers, a capping layer, microcavities through the conductor layers and the capping layer, a cavity connecting the microcavities, and an electrolyte filling in the space created by the cavity and the microcavities in the substrate. The microcavities allow gases to pass through but retain the electrolyte through surface tension.

摘要： The invention disclosed herein relates to a dry sensor for measuring the concentration of an analyte in a liquid beverage sample. Described herein is a novel dry sensor which is able to receive a liquid sample and adjust the pH of the liquid to be suitable for assaying an analyte of interest without the need to add reagents to the sample and/or to perform manually timed operations and able to detect a redox reaction in the presence of a liquid sample. The meter disclosed herein, when connected to the sensor disclosed herein is able to adjust the temperature of the liquid to be suitable for the assay, apply a series of potentials, measure the current at several times, measure the diffusion coefficient of the limiting electrochemical species, calculate the concentration of one or more analytes, and rapidly provide the user with the required information on the liquid sample.
