    摘要: A sensor system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes a connection detection device, a power source, and a delay circuit. The connection detection device determines if the sensor electronics device is connected to the sensor and transmits a connection signal. The delay circuit receives the connection signal, waits a preset hydration time, and couples the regulated voltage from the power source to an electrode in the sensor after the preset hydration time has elapsed. Alternatively, the sensor electronics device may include an electrical detection circuit and a microcontroller. The electrical detection circuit determines if the plurality of electrodes are hydrated and generates an interrupt if the electrodes are hydrated. A microcontroller receives the interrupt and transmits a signal representative of a voltage to an electrode of the plurality of electrodes.

    摘要: The disclosure provides methods for fabricating a long-term analyte sensor for measuring at least one analyte in the body of a user. The analyte sensors made by these methods include a plurality of analyte contacting sensor elements and at least one structure for relaying information to and from the sensor. The analyte sensor so fabricated further includes at least one sensor protection membrane that is controllable in a manner such that sensor elements may be activated (e.g. exposed to the external environment) at different times so as to extend the useful life of the sensor. In illustrative analyte sensors, the analyte is glucose.

    摘要: The disclosure provides a sensor including a sensor having an external surface and a cannula. The cannula comprises a substantially cylindrical wall encircling a lumen, at least one aperture and a distal end. The sensor is positioned within the lumen and the distal end of the cannula extends beyond the sensor. This configuration functions for example to stabilize chemical reactions associated with the sensor by creating a buffer zone between the sensor and the surrounding tissues at the site of implantation. In certain embodiments, the sensor can further comprise an accessory material in proximity to the external surface, wherein the accessory material modifies the biological response of a tissue that is in contact with the sensor. The sensor can also comprise anchors that keeps the sensor in contact with subcutaneous tissue of a subject upon insertion of the sensor into the body of the subject.
