Abstract: An ingestible electronic capsule for the collection of samples along a gastric intestinal tract and methods relating thereto are provided. The ingestible electronic capsule includes a housing and a cap that form an interior chamber. The cap includes a sampling port and one or more sample collection chambers are disposed within the interior chamber. A motor is also disposed within the interior chamber and is configured to rotate one of the cap and the one or more sample collection chambers so to align one or the one or more sample collection chambers and the sampling port of the cap so to allow for sample collection. A microcontroller is also disposed within the interior chamber and is in communication with at least the motor. The microcontroller is configured to control the selective alignment of the sampling port and one of the one or more sample collection chambers and induce gastric intestinal fluid sampling.
