Method and apparatus for transmitting power and data using the human body

Method and apparatus for transmitting power and data using the human body, United States Patent 6754472, by Microsoft 2004.

Methods and apparatus for distributing power and data to devices coupled to the human body are described. The human body is used as a conductive medium, e.g., a bus, over which power and/or data is distributed. Power is distributed by coupling a power source to the human body via a first set of electrodes. One or more devise to be powered, e.g., peripheral devices, are also coupled to the human body via additional sets of electrodes. The devices may be, e.g., a speaker, display, watch, keyboard, etc. A pulsed DC signal or AC signal may be used as the power source. By using multiple power supply signals of differing frequencies, different devices can be selectively powered. Digital data and/or other information signals, e.g., audio signals, can be modulated on the power signal using frequency and/or amplitude modulation techniques.

Why not?
The humman body uses electricity produced chemically through the nerves.
It could just use the same system.

The main question : could THIS be patented? Coud a physical, mechanical or biological property be patented... Distrubing...
