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. An 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.
Claims42
A method of using radio frequency identification (RFID) in diabetes management, comprising:
- sending a first radio wave from an RFID reader to an RFID sensor of an analyte sensing device having an in vivo analyte sensor partially or fully implanted in a body;
- receiving the first radio wave at the RFID sensor;
- sending a second radio wave from the RFID sensor back to the RFID reader in response to reception of the first radio wave, wherein the second radio wave includes diabetes information of the in vivo analyte sensor;
- receiving the second radio wave at the RFID reader;
- and
- reading the diabetes information in the second radio wave at the RFID reader.
