Analyte sensor

A method of using a sensor to measure an analyte in a medium within a living animal, the method comprising:

• controlling the sensor elements of the sensor to generate a first analyte measurement signal using power provided by a charge storage device of the sensor while an inductive element of the sensor is not in an electrodynamic field generated by an external device, wherein the sensor elements are configured to generate the first analyte measurement signal based on a detectable property exhibited by an analyte indicator of the sensor, and the analyte indicator is configured to exhibit the detectable property based on the amount or concentration of the analyte in the medium;
• generating first measurement information based on the first analyte measurement signal;
• and
• controlling an input/output circuit of the sensor to wirelessly convey the first measurement information to the external device via the inductive element while the inductive element is in an electrodynamic field generated by the external device.

A sensor for implantation within a living animal and measurement of an analyte in a medium within the living animal, the sensor comprising:

• an analyte indicator configured to exhibit a detectable property based on the amount or concentration of the analyte in the medium;
• sensor elements configured to generate an analyte measurement signal based on the detectable property exhibited by the analyte indicator;
• a measurement controller;
• a non-volatile storage medium;
• a charge storage device;
• and
• a measurement scheduler that is powered by the charge storage device and is configured to issue an autonomous measurement command;
• wherein the measurement controller is configured to:
• (i) control the sensor elements to generate a first analyte measurement signal using power provided by the charge storage device in response to the autonomous measurement command;
• (ii) generate first measurement information based on the first analyte measurement signal;
• and
• (iii) store the first measurement information in the non-volatile storage medium.
