Abstract

Claims (36)

1 . A system, comprising:

an analyte sensor configured to be in fluid contact with bodily fluid under a skin surface, and to generate signals corresponding to monitored analyte level;

sensor electronics operatively coupled to the analyte sensor, the sensor electronics comprising a communication module and a data packet generator to generate one or more data packets including information comprising at least one of analyte related data and sensor related data; and

a receiving device, the receiving device comprising a display, one or more processors, and a memory storing instructions which, when executed by the one or more processors, cause the one or more processors to:

when the receiving device is within a predetermined range of the sensor electronics, receive the one or more data packets from the sensor electronics;

determine whether the information has been received;

determine whether the receiving device has been within the predetermined range of the sensor electronics for at least a predetermined period of time; and

in response to determining that the information has been received and that the receiving device has been within the predetermined range of the sensor electronics for at least the predetermined period of time, provide a notification on the display of the receiving device corresponding to the information;

wherein the system does not require calibration by a human intervention during a usage life of the system.

2 . The system of claim 1 , wherein the information comprises at least one of an operational status of the sensor, an operational status of the sensor electronics, or a battery life status.

3 . The system of claim 2 , wherein the one or more data packets further include historical analyte data, and wherein the receiving device further stores instructions which, when executed by the one or more processors, cause the one or more processors to provide a historical representation of the historical analyte data on the display.

4 . The system of claim 1 , wherein the notification comprises an alarm.

5 . The system of claim 4 , wherein the alarm is for notifying a user about an adverse condition associated with the analyte sensor.

6 . The system of claim 1 , wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

7 . The system of claim 6 , wherein the analyte-responsive enzyme is chemically bonded to the polymer.

8 . The system of claim 6 , wherein the working electrode further comprises a mediator.

9 . The system of claim 1 , wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.

10 . The system of claim 9 , wherein the mediator is chemically bonded to the polymer.

11 . The system of claim 1 , wherein the analyte sensor comprises a glucose sensor.

12 . The system of claim 1 , wherein the analyte sensor comprises one of a ketone sensor, a lactate sensor, and an oxygen sensor.

13 . A method, comprising:

receiving, at a receiving device, one or more data packets including information comprising at least one of analyte related data and sensor related data from a sensor electronics over a wireless communication link when the receiving device is within a predetermined range of the sensor electronics, the sensor electronics operatively coupled to an analyte sensor configured to be in fluid contact with bodily fluid under a skin surface;

determining that the information has been received;

determining that the receiving device has been within the predetermined range of the sensor electronics for at least a predetermined period of time; and

in response to determining that the information has been received and that the receiving device has been within the predetermined range of the sensor electronics for at least the predetermined period of time, providing a notification on a display of the receiving device corresponding to the information.

14 . The method of claim 13 , wherein the information comprises at least one of an operational status of the sensor, an operational status of the sensor electronics, or a battery life status.

15 . The method of claim 14 , wherein the one or more data packets further include historical analyte data, and further comprising providing a historical representation of the historical analyte data on the display.

16 . The method of claim 13 , wherein providing the notification comprises providing an alarm.

17 . The method of claim 16 , wherein the alarm is for notifying a user about an adverse condition associated with the analyte sensor.

18 . The method of claim 13 , wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

19 . The method of claim 18 , wherein the analyte-responsive enzyme is chemically bonded to the polymer.

20 . The method of claim 18 , wherein the working electrode further comprises a mediator.

21 . The method of claim 13 , wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.

22 . The method of claim 21 , wherein the mediator is chemically bonded to the polymer.

23 . The method of claim 13 , wherein the analyte sensor comprises a glucose sensor.

24 . The method of claim 13 , wherein the analyte sensor comprises one of a ketone sensor, a lactate sensor, and an oxygen sensor.
