  • Patent number: 10660555
    Abstract: A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.

  • Publication number: 20190338339
    Abstract: Embodiments of the invention provide methods and materials for making analyte sensors having a plurality of layered elements such as amperometric glucose sensors that are used by diabetic individuals to monitor blood sugar concentrations. Embodiments of the invention utilize plasma deposition technologies to form thin films of adhesion promoting compositions useful in such sensors. Sensors that incorporate the thin film compositions formed by these processes exhibit a number of desirable characteristics.
