A sensor, system, and method for detecting and correcting for changes to an analyte indicator of an analyte sensor. The analyte indicator may be configured to exhibit a first detectable property that varies in accordance with an analyte concentration and an extent to which the analyte indicator has degraded. The analyte sensor may also include a degradation indicator configured to exhibit a second detectable property that varies in accordance with an extent to which the degradation indicator has degraded. The analyte sensor may generate (i) an analyte measurement based on the first detectable property exhibited by the analyte indicator and (ii) a degradation measurement based on the second detectable property exhibited by the degradation indicator. The analyte sensor may be part of a system that also includes a transceiver. The transceiver may use the analyte and degradation measurements to calculate an analyte level.

A method for treating a human subject suffering from a gastrointestinal disorder using a non-dissolvable ingestible capsule, the method including providing the non-dissolvable ingestible capsule to the subject, and subsequently, ingesting the non-dissolvable ingestible capsule by the subject, wherein passage of the non-dissolvable ingestible capsule through the gastrointestinal tract of the subject treats the gastrointestinal disorder, and wherein the non-dissolvable ingestible capsule may be at least one of: a non-vibrating capsule, a capsule that is devoid of any electronic components, and a capsule that is devoid of any mechanical moving components.

Disclosed is an implant and method of making an implant. The implant having a housing that defines a cavity. The housing includes a sensor comprising a base attached to a diaphragm wherein said base may be positioned within said cavity. The sensor may be a capacitive pressure sensor. The diaphragm may be connected to the housing to hermetically seal said housing. The sensor may include electrical contacts positioned on the diaphragm. The attachment between the base and the diaphragm may define a capacitive gap and at least one discontinuity configured to enhance at least one performance parameter of said implant.

An intra-uterine monitoring system is described. The system comprises an implantable sensor device, shaped and dimensioned for implantation in a uterus for measuring conditions within the uterus to generate sensor data, and a wearable receiver device, for wirelessly receiving the sensor data generated by the implantable sensor device. In this way, real-time, in-vivo monitoring of the intra-uterine environment can be performed. The implantable sensor device can be kept small and simple, requiring only the mechanical and electronic structures necessary to take sensor measurements and transmit those to the receiver device. By making the receiver device wearable, it can be kept in relatively close proximity to the implantable sensor device on a long-term basis, making regular monitoring viable.
