Masticable ingestible product and communication system therefor

A method of manufacturing an ingestible product, the method comprising:

• accessing an ingestible device comprising:
• a framework;
• a first and a second material that are dissimilar to one another and are both deposited onto the framework, the first and second materials configured to produce a current path when both come into contact with the conductive fluid;
• and
• a control device coupled to the first and second materials and configured to alter the current path to create a detectable signal;
• enveloping at least both the first and second materials of the ingestible device in a protective layer;
• at least partially filling a capsule with a gel or liquid;
• and
• suspending the ingestible device within the gel or liquid of the capsule;
• wherein:
• the protective layer is configured to prevent the ingestible device from being powered on by the gel or liquid while in the capsule;
• the protective layer is configured to dissolve after being ingested by a patient to release the ingestible device when inside the patient;
• the ingestible device is configured to be powered on when in contact with a conduct fluid;
• and
• the ingestible device is configured to communicate information when powered on.
