we need power for daily human life..
currently as the demands of technology growth we need much power to replace man by machine..

in developing countries power is big deal, no power due to dependency on now drying rivers(HEP)..
solar and natural gas have been found the solution but still developing countries have not succeeded to have enough power..
in communications,mobile phones needs power..almost to the maximum of 5Vdc..(3.7-5)v dc..

I thought of extracting power from the human body as far as the electrode potential of our bodies will generate some Millivolts
which we need to amplify and obtain enough power to even charge cellphone battery and keep communications constancy in remote areas..(in developing countries)

my challenge is to get surface electrodes(surface electrodes)that will generate reasonable current/voltage..
with this i can design battery charger that is universal and applicable any where in this world..

so please, members send me your suggestions on which kind of electrodes i can use
