Assignee: DEXCOM, INC.
Field: Measurement (Instruments)
Classification: CPC G  A | IPC A  G

Claim 0:
1. A device for continuous in vivo measurement of glucose concentrations in a host, comprising:
a first electrode;
a second electrode;
a first membrane located over at least a portion of the first electrode, the first membrane comprising an enzyme configured to catalyze a reaction of glucose and oxygen from a biological fluid in contact with the first membrane in vivo, the first membrane having a first temperature coefficient;
a second membrane located over at least a portion of the second electrode, the second membrane having a second temperature coefficient different than the first temperature coefficient; and
electronic circuitry operatively connected to the first electrode and to the second electrode, the electronic circuitry being configured to generate a signal representative of a concentration of glucose in the host and configured to measure at least one of an in vivo temperature or a change in temperature in vivo, the measuring using the first membrane and the second membrane.
