Power your mobile just by holding it? (in Off-topic)
amazing stuff and times we live in.

Well, yes...as soon as they make a mobile that runs on 200 millivolts.
Last I checked, my iPhone runs on a 3.7 V unit (3700 millivolts).
This article is less about the power generation and more about the creation of technologies that simply use less power (and can therefore be run on the tiny amounts of electromotive force generated by the temperature difference our skin can create).
You can only bend the Laws of Thermodynamics so far. *smile* Any more than that and the ghost of Carnot comes out and shows you a new type of cycle.

iPhone is more of a computer than a phone.

That being as it may, "mobiles" don't wun on tiny amounts of power (like 200 mV). Three-point-six and 3.7 V battery packs are common for Motorola and Samsung phones, for example.
So the answer to GL's subject line is still "no". I would say kinetic power (like the watches that are powered by body motion) would provide more power than the warmth of skin.
i was thinking it would be very useful for medical devices implanted in the body that now require surgery for battery changes. i have no idea what kinda voltage pacemakers and subcutaneous tens units use though.
If it will make the sub-q tens unit a vanity procedure, I'm all for it. :D

I think those are exactly the types of things that this breakthrough is getting into the "Powered by Body" power range... So, definitely an exciting thing! When you think about things like implants, prosthetics, and temporary sensors, this could really make a lot of things more "organically" autonomous. Imagine having to eat a little more or having a little more appetite because your body is powering these extra units! Heck, it might even be a way of burning calories someday! *smile*
