Human Body Transmits Audio


Sony's research lab in Tokyo have invented a new kind of wireless headphone and have put in a patent application for the technology.
The idea is that there is no need for Bluetooth or infra-red communication – the audio signal is fed straight through the listener's body!
The system apparently uses the listener’s body as a capacitor with a few millions of an amp flowing through. If you want to check out the technical details, take a look at the New Scientist article which has a link to the actual patent application.
