Abstract: Methods, systems, and devices for continuous glucose monitoring. More particularly, the methods, systems, and devices describe a working electrode with a GOx sensor and a background electrode in which the background electrode has no GOx sensor. The system may then compare the first signal and the second signal to detect ingestion of a medication by the user. The system may generate a sensor glucose value based on the comparison.

Abstract: A glucose biosensor encasement includes a first membrane and a second membrane. The first membrane has a first interlocking segment. The second membrane has a second interlocking segment cooperating with the first interlocking segment of the first membrane to provide a cavity between the first membrane and the second membrane configured to receive a glucose sensor. At least one of the first membrane and the second membrane comprises a semi-permeable portion configured to regulate diffusion characteristics of glucose through the membrane to realize a sensitivity for a sensor in the cavity. A method is also provided.

Abstract: An electrochemical sensor including a working electrode having an arrangement of pillars defining channels between the pillars. The channels increase confinement of a byproduct produced in an electrochemical reaction used during sensing of an analyte, so as to increase interaction of the byproduct with the working electrode. A number of working embodiments of the invention are shown to be useful in amperometric glucose sensors worn by diabetic individuals.
