I did not see anything about "Sweat Batteries" on the link.
That's ok, but I am not sure how they would work.
So, a couple of questions:
Do you connect 9-people in series? or how do you get 9-cells connected together on the same person?
A Minty Boost pulls lots of mA's from AA cells when operating.
Will you be able to supply enough current from your "Sweat Batteries" to run a Minty Boost?

The Minty Boost wants less than 5-V to operate properly.
