Body-wired headphones

Sony's Tokyo research lab has found a way to connect headphones to portable music and video players without the need for fiddly wiring. They simply feed an audio signal straight through the listener's body. Another patent find by wonderful Barry Fox for New Scientist.

"The new system uses the listener's body as a capacitor that carries a tiny electrostatic charge. A music or video player sends a fluctuating signal to a conductive cloth pad – such as a wrist band – and this slightly charges the wearer's body. A pair of conductive ear pads in the headphones pick-up the signal and rapidly convert it back into sound."
