a capsule;
a gel or liquid contained within the capsule;
an ingestible device suspended within the gel or liquid, the 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;
the ingestible device configured to:
be powered on when in contact with a conductive fluid; and
communicate information when activated; and
an ingestible protective layer enveloping at least both the first and second materials of the ingestible device and configured to:
prevent the ingestible device from being powered on by the gel or liquid within the capsule by preventing the gel or liquid of the capsule from contacting both the first and second materials; and
dissolve after being ingested by a patient to release the ingestible device when inside the patient.
