Skin-based Communication

According to Ident Technology -- "the skin is the largest organ of the human body. It is the physiological border between our body and the environment. Thereby it protects us from harmful influences from the outside. At the same time we receive feelings of heat and cold, but also tenderness or pain. So our skin has to fulfil a great variety of tasks." Ident Technology's Skinplex enables the human skin to be used as a mechanism for communication. Skinplex enables both the active transmission of information through (alongside) the skin and the passive identification of any changes in the electrical field produced by a human being. Essentially, a detector worn close to the skin can measure changes in an electric field, the field being induced via an oscillator worn along another part of the body -- and used as a transmission device. Japan's Red Tacton has been attempting to do the same. RedTacton have products that can transmit 10Mbps across the human skin! RedTacton has a brief explanation about how their product works. Fascinating!
