Techniques For Tracking Ingestible Device

A method for tracking an ingestible device in a gastrointestinal tract of a subject, comprising:

• measuring, by an accelerometer disposed in the ingestible device, acceleration of the ingestible device as it traverses through the gastrointestinal tract;
• wirelessly communicating acceleration measurements from the ingestible device to another device outside of the gastrointestinal tract;
• computing, by a processor of the another device, a metric from the acceleration measurements;
• and
• identifying, by the processor, the location of the ingestible device in the gastrointestinal tract based in part on the metric.

An ingestible device for traversing a gastrointestinal tract, comprising:

• a housing configured to be ingested by a subject;
• an accelerometer disposed inside the housing and operable to measure acceleration of the ingestible device as it traverses through the gastrointestinal tract of the subject;
• and
• a microcontroller residing in the housing and interfaced with the accelerometer, wherein the microcontroller is configured to computer a metric from the acceleration measurements obtained by the accelerometer over a period of time and identify a location of the ingestible device in the gastrointestinal tract based on the metric.
