The
latest purpose-designed thermoelectric batteries are able to generate voltages
of around 450 millivolts from a temperature gradient of just 1K. There is no electrolysis
involved.
Instruments are able to detect the electromagnetic fields produced by the thermoelectric currents established in inhomogeneous mixtures of conductive materials when subject to temperature gradients. There is no electrolysis involved.

Research carried out at the UK’s National Research Laboratory to investigate the effects of electromagnetic fields on the human head were carried out using a model which contained no physical representation of either the human neurological system or any metal amalgam dental fillings, perhaps the two most electromagnetically sensitive components of the majority of people’s heads.

And scientists might therefore be unable to judge with any degree of confidence whether or not the following is significant:
"Obviously the glasses in question would have been a few centimetres away from the user's eyes, but it would be interesting to have the experiments repeated taking measurements from amalgam dental fillings which are actually in the body. Many mobile users report burning sensations and toothache in teeth with fillings and also an unpleasant metallic taste in their mouth. There have also been anecdotal reports from UK National Health staff of a marked increase in the incidence of jaw cancer, which won't show up in official statistics for several years yet."
