All right, this is just a reference but very interesting. If you haven't heard of Earthing, you may want to look into it. It's not new technology, but supposedly restores regular circadian rhythms and cortisol levels, along with providing a host of other benefits.
I bought a multimeter and made my own homemade device with an outdoor grounding rod, and based on voltage measurements through my body, it does knock out the voltage which ranged between 3 and 10 volts depending on whether I was near an electrical source such as a cord. http://www.naturesplatform.com/earthing.html
