Abstract
A health monitoring system that monitors the health of a patient includes an ingestible capsule containing a medication to be consumed by a subject. A signal generator located within the capsule outputs an electrical signal having a predetermined characteristic indicative of said medication, said capsule and said medication being liberated by dissolution of the capsule in the stomach acid of a subject. A signal detector, preferably having an input in electrical contact with a portion of the subject's skin, is used to detects the electrical signal. This allows the ingestion of the medication to be tracked.
