Ingestible device, a system and a method for analysis of the gastrointestinal tract and a wearable device for localization of an ingestible device

A wearable device for localization of an ingestible device, the wearable device comprising:

• a magnetic field transmitter configured for generating an alternating magnetic field to be received by a magnetic field sensor comprised in the ingestible device, the magnetic field is configured for generating spatial location data representing a spatial localization of the ingestible device while the ingestible device passes through the gastrointestinal tract;
• a receiving sensor configured for receiving information of the spatial localization of the ingestible device from the magnitude and relative sign of the magnetic field received by the magnetic field sensor and further configured for receiving the anatomical localization from biochemical parameter data acquired by the ingestible device while the ingestible device passes through the gastrointestinal tract;
• wherein the wearable device is configured to calculate a combined localization of the ingestible device in the gastrointestinal tract based on the anatomical localization and the spatial localization.

A method for analysis of the gastrointestinal tract, the method comprising:

• receiving a biochemical parameter from the ingestible device, while the ingestible device passes through the gastrointestinal tract, said biochemical parameter providing an anatomical localization of the ingestible device;
• receiving information of the magnitude and relative sign of an alternating magnetic field from a magnetic field sensor comprised in an ingestible device, while the ingestible device passes through the gastrointestinal tract, wherein the information of the magnitude and relative sign of the alternating magnetic field comprises spatial location data representing a spatial localization of the ingestible device;
• determine a combined localization of the ingestible device in the gastrointestinal tract based on the anatomical localization and the spatial localization.
