System and method for an ingestible physiological monitor

A method for internal monitoring, the method comprising:

• ingesting an ingestible system, the ingestible system comprising a capsule and a physiological monitor, the physiological monitor comprising:
• a substrate;
• at least one physiological sensor coupled to the substrate;
• a controller coupled to the substrate and configured to receive physiological data and prepare the physiological data for one of transmission from a subject or analysis of the physiological data;
• wherein the substrate of the physiological monitor is folded, such that the physiological monitor is bent over itself so that one part of the physiological monitor covers another part of the physiological monitor thereby creating a folded physiological monitor that is placed in the capsule to be ingested by a subject;
• dissolving the capsule in a portion of an intestine of the subject to release the folded physiological monitor in the portion of the intestine;
• and
• unfolding the folded physiological monitor in the portion of the intestine.

An ingestible system comprising:

• a substrate;
• and
• a physiological sensor coupled to the substrate, the physiological sensor being at least one of a pair of electrodes, or a pulse oximeter;
• wherein the ingestible system is configured to adhere to a lining of an intestine of a subject when the ingestible system contacts the lining of the intestine of the subject;
• and
• wherein when the ingestible system is adhered to the lining of the intestine of the subject, the physiological sensor is configured to capture physiological data of the subject, the physiological data including at least one of an ECG signal, an impedance signal, a respiratory signal, or a blood oxygenation parameter.
