Abstract
Embodiments that translate a sensor measurement to a frequency characteristic are disclosed. The frequency characteristic can be wirelessly detected by a reader device. The detected frequency characteristic can be used to determine the corresponding sensor measurement. Devices utilizing this approach can be characterized or calibrated to increase accuracy. Systems and methods utilizing the approaches are also described.
Claims21
1-108. (canceled)
A device for detecting an analyte sensor measurement, comprising:
- a housing;
- an analyte sensor adapted to output an electrical current or voltage that corresponds to an analyte level of a user, wherein the analyte sensor is configured for in vivo analyte monitoring and comprises a first portion located partially outside of the housing and a second portion located partially within the housing, and wherein the first portion comprises two or more electrodes for contact with the user's bodily fluid;
- and
- sensor electronics located within the housing, the sensor electronics comprising non-transitory memory and a circuit coupled with the analyte sensor, wherein the circuit has a frequency characteristic adapted to vary according to the electrical current or voltage output by the analyte sensor.
1 more element
A reader device for detecting an analyte sensor measurement, comprising:
- processing circuitry;
- and non-transitory memory on which is stored a plurality of instructions that, when executed, cause the processing circuitry to cause propagation of a plurality of sweep frequencies to a sensor device, detect a frequency characteristic of the sensor device, and determine an analyte level of a user of the sensor device based on the detected frequency characteristic.
