Abstract: Devices and methods for measuring a concentration of a target analyte in a biological fluid in vivo are provided herein. In some examples, a device includes an indwelling sensor and sensor electronics. The sensor may include a substrate; a first electrode disposed on the substrate; an ionophore disposed on the substrate to selectively transport the target ion to or within the first electrode; and a second electrode disposed on the substrate. The sensor electronics is configured to generate a signal corresponding to an electromotive force which is at least partially based on a potential difference that is generated between the first electrode and the second electrode responsive to the ionophore transporting the target ion to the first electrode.

Abstract: Disclosed herein are systems and methods for a continuous analyte monitoring system for measuring a concentration of a first analyte and concentration of a second analyte in a host. One such system utilizes a working electrode and a reference electrode to measure glucose concentration and oxygen concentration in bodily fluid of a host. The system includes a sensor control circuit that applies a first bias condition to the sensor to measure a first signal generated by the sensor indicative of a concentration of the first analyte. The sensor control circuit also applies a second bias condition to the sensor to measure a second signal generated by the sensor indicative of a concentration of a second analyte at the host.
