First Claim
Patent Images
1. A sensor system for measuring an analyte concentration in a host, the sensor system comprising:
- a sensor comprising at least one electrode; and
sensor electronics configured to measure the analyte concentration in the host when the sensor is implanted therein, wherein the sensor electronics comprise a data sampling portion in data communication with the at least one electrode, wherein the data sampling portion comprises an analog portion configured to measure the current flowing at the at least one electrode and to convert the current measurement to digital values representative of the current, wherein the digital values are acquired at a predetermined time interval, and wherein the predetermined time interval is programmed to be programmable after the sensor electronics have been manufactured.
