1. A sensor comprising:
an analyte indicator configured to exhibit a detectable property based on an amount or concentration of an analyte in a medium within a living animal;
one or more sensor elements configured to generate an analyte measurement signal based on the detectable property exhibited by the analyte indicator;
an input/output circuit configured to wirelessly convey measurement information to an external device;
a measurement controller;
a charge storage device;
a clock that is powered by the charge storage device;
a measurement scheduler that is powered by the charge storage device and configured to use an output of the clock to periodically determine that an interval of time has passed; and
a power switch configured to switch the one or more sensor elements, the input/output circuit, and the measurement controller from not being powered by the charge storage device to being powered by the charge storage device if the measurement scheduler has determined that the interval of time has passed,
wherein the measurement controller is configured to:
(i) control the one or more sensor elements to generate the analyte measurement signal using power provided by the charge storage device;
(ii) generate measurement information based on the analyte measurement signal; and
(iii) control the input/output circuit to wirelessly convey the measurement information to the external device.
