Sony put in patent application for body-powered wireless headphones 29/11/06
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 â€“ the audio signal is fed straight through the listener's body!
The system apparently uses the listenerâ€™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. More information:
