摘要： A sensor having a sensor head including a unibody construction, a first electrode, and at least one second electrode is provided. The first electrode can include a first pair of sensing elements coupled to each over via at least one bridge element extending from a first sensing element to a second sensing element. The at least one second electrode can include a second pair of sensing elements interleaved with the first pair of sensing elements. The second pair of sensing elements can be coupled to each other via at least one second bridge element extending from a third sensing element to a fourth sensing element. A method of manufacturing the sensor is also provided.

摘要： A method for determining a health indicator parameter of a fluid are described. The method can include contacting at least one first functionalized electrode included in a plurality of functionalized electrodes of a sensing unit with a fluid. The method can also include generating a first electrical signal within the fluid by the at least one first functionalized electrode. The method can further include receiving, by at least one second functionalized electrode included in the plurality of functionalized electrodes of the sensing unit, a second electrical signal in response to the first electrical signal. The sensing unit can determine a health indicator parameter of the fluid based on the second electrical signal. The health indicator parameter can be associated with an electrochemical response signal included in the second electrical signal. The sensing unit can provide the health indicator parameter to a computing device communicably coupled to the sensing unit.

摘要： A method includes receiving an output signal from a conductive element configured within a dielectric material. The conductive element can have an input voltage applied thereto and the output signal can include a plurality of signal amplitudes indicative of electric charges discharged across a gap between the conductive element and the dielectric material in response to the applied input voltage. The method can also include determining charge characterization data and classifying a material and a geometry of the conductive element and/or the dielectric material. The classification can include an operational state of the conductive element and/or the dielectric material. Related systems, apparatuses, and non-transitory computer readable mediums are also described.

摘要： Sensor circuitry utilizing feedback to balance sensor output data is provided. An apparatus can include a primary coil and a first secondary coil outputting a first voltage. The apparatus can also include a second secondary coil outputting a second voltage. The apparatus can further include circuitry coupled to the first secondary coil and the second secondary coil. The circuitry can be configured to receive the first voltage from the first secondary coil and the second voltage from the second secondary coil. The circuitry can also be configured to determine a feedback voltage based on a difference between the first voltage and the second voltage. The feedback voltage can correct the difference. The circuitry can also modify a third voltage that can be output by the circuitry to be zero based on the feedback voltage.
