Abstract: Techniques disclosed herein relate to determining a calibrated measurement value indicative of a physiological condition of a patient using sensor calibration data determined based on fabrication measurements. In some embodiments, the techniques involve obtaining one or more electrical signals from a sensing element of a sensing arrangement, where the one or more electrical signals are influenced by a physiological condition in a body of a patient; obtaining calibration data associated with the sensing element, where the calibration data is based on fabrication process measurement data for the sensing element and a calibration model for a certain physiological condition; and determining, using the one or more electrical signals and the calibration data associated with the sensing element, a calibrated output value indicative of the physiological condition.

Abstract: Medical devices, systems and methods are provided. One method involves obtaining fabrication process measurement data for a plurality of instances of a sensing element, obtaining reference output measurement data from the plurality of instances in response to a reference stimulus, determining a predictive model for a measurement output of the sensing element as a function of fabrication process measurement variables based on the relationship between the fabrication process measurement data and the reference output measurement data, generating a simulated output measurement distribution across a range of the fabrication process measurement variables using the predictive model, identifying performance thresholds for the measurement output based on the simulated output measurement distribution, obtaining output measurement data from the instance of the sensing element in response to the reference stimulus, and verifying the output measurement data satisfies the performance threshold prior to calibrating a subsequent instance of the sensing element.

Abstract: A method of depositing of a film on a substrate with controlled adhesion. The method comprises depositing the film including metal, wherein the metal is deposited on the substrate using physical vapor deposition at a pressure that achieves a pre-determined adhesion of the film to the substrate. The pre-determined adhesion allows processing of the film into a device while the film is adhered to the substrate but also allows removal of the device from the substrate.

Abstract: A single flex double-sided electrode useful in a continuous glucose monitoring sensor. In one example, a counter electrode is placed on the back-side of the flex and a work electrode is placed on the top-side of the sensor flex. The electrode is fabricated on physical vapor deposited metal deposited on a base substrate. Adhesion of the electrode to the base substrate is carefully controlled so that the electrode can be processed on the substrate and subsequently removed from the substrate after processing.
