RISC Partners' correspondent in Japan, Pierre Mustière, has been talking to us about it for a while. Japanese mega-corp NTT has developped a technology, RedTacton, to enable communications between devices at speeds up to 2 Mbps, using the human skin as a network for devices within 20cm from the skin... I hear NTT DoCoMo is looking to finance projects using this technology.
The official RedTacton site is here. The Register is running a story here.
