The method further involves determining a measurement value using the calibrated measurement parameter as input to a performance model. The performance model is derived from historical calibrated measurement parameters and corresponding reference values. The historical calibrated measurement parameters are from other instances of the sensing element. A command is then determined based on the measurement value and sent to a medical device. The command causes the medical device to deliver a dose of medication influencing the physiological condition of the person.Type: ApplicationFiled: April 7, 2023Publication date: August 3, 2023Inventors: Akhil Srinivasan, Peter Ajemba, Steven C.

Patent number: 11311215Abstract: The invention includes method and materials designed to measure the material properties (e.g. thickness) of layers of material in a sensor using non-Faradaic EIS (Electrochemical Impedance Spectroscopy) methods. The methods are non-destructive, very sensitive and rapid. Typically in these methods, an AC voltage is applied to the desired material layer while the output current and therefore impedance is measured. This voltage can be applied in multiple frequencies in sweep mode in order to detect both the material and, for example, the thickness of the target material. In this way, EIS allows the characterization of properties of various layers of material disposed in devices such as electrochemical glucose sensors.Type: GrantFiled: April 4, 2019Date of Patent: April 26, 2022Assignee: MEDTRONIC MINIMED, INC.Inventors: Chi-En Lin, David Probst, Mohsen Askarinya, Akhil Srinivasan, Melissa Tsang, Michael E.
