摘要：
The present invention may be embodied as an ingestible device capable of sensing one or more chemical parameters. In use, the device can continuously determine the chemical concentrations within an alimentary canal tract. An embodiment of the device comprises a housing resistant to degradation by alimentary canal fluid, a light source, and image capture device. An analyte sensor is configured to obtain at least one measurement of a concentration of analyte in the fluid. The analyte sensor comprises a sensor substance in a sol-gel material so the sensor substance reversibly interacts with an analyte of interest. In addition, the analyte sensor is configured to generate a trigger signal for controlling the operation of subsystems in the device.
