Human Antenna

A neat article about using the human body as an antenna to control your lights, HVAC, or even act as a remote control.
"The experiments showed that electromagnetic noise is so predictable that it can be used it to figure out where a person is standing, what the person is doing, and even where a hand is placed on a wall. The team used a simple sensor that was essentially just a piece of metal, but Morris said that ultimately a sensor could be placed in the user's hand or anywhere else that the radio signals being picked up by the body can be gathered."
It wasn't what I was expecting based on the headline... I was hoping to run full legal power through my fingers to make contacts on 80M. Okay, that's unreasonable. How about 40M QRP?
