I think I can still feel my fingers tingling after I played with a stereo hooked up to Ericsson’s new capacitive coupling technology, which uses the water in the human body to transmit data instead of cables or radio waves.
In Ericsson’s booth demo, you’re presented with two transmitter boxes with flat metal connections in front of them. One of the boxes is connected to an audio source, and the other to a set of speakers. When you put your hands firmly down on both of the connections, music plays like magic from the speakers. Ericsson told me it plan to try to sell this technology to device manufacturers in future chipsets, assuming anyone is interested.
And I was only joking before. You can’t feel a thing.
