We answered this question on the show...



Andrew -   Yes, that is quite possible.  Humans are 30-35 degrees C versus the ambient temperature of maybe 20-25 degrees C.  A small temperature difference is sufficient to generate a small amount of power and electronics are getting more and more efficient; we are now down at microwatt level for various things.  So yes, you could quite feasibly have human powered electronics using TEGs as the mechanisms for that power.

its called bioelectric energy
