This could potentially power a low power beacon every so often. It doesn't seem practical for IOT wearables or for anything industrial at that power density. I'd be curious about the cost, in particular what manufacturing process size can be used for this. 1cm² of wafer can still be quite pricey at .000012 watts.
5°C Delta T generation is pretty impressive though. There are some commercial systems that can operate with 60°C temperature Delta (organic rankine cycle) and recover about 12% of that energy.

Even if it is only half as efficient, it should be a lot cheaper and possibly strong enough to be laminated into fabric like e.g. Gore-Tex membranes (extruded microporous PTFE film). A reverse electric blanket would be fancy...
