Abstract
A glucose monitoring system, includes a glucose sensor strip or package of strips. The strip includes a substrate and a glucose monitoring circuit that has electrodes and a bodily fluid application portion of selected chemical composition. An antenna is integrated with the glucose sensor strip. A RFID sensor chip is coupled with the glucose sensor strip and the antenna. The chip has a memory containing digitally-encoded data representing calibration and/or expiration date information for the strip.
Claims23
An analyte monitoring system, comprising:
- an analyte sensor;
- an antenna integrated with the analyte sensor;
- an radio frequency identification (RFID) sensor chip coupled with the analyte sensor and the antenna, the RFID sensor chip including a memory for storing digitally-encoded data representing a monitored analyte level detected by the analyte sensor;
- and
- an RFID reader coupled to a housing and configured to transmit an radio frequency (RF) signal and to receive data from the RFID sensor chip, the RFID reader further configured to provide an RF power signal;
- wherein the digitally encoded data representing the monitored analyte level is detected by the RFID reader based a backscattering radio wave from the RFID sensor chip when the RFID reader is positioned within a predetermined distance from the RFID sensor chip.
