Human arm transmits broadband signals

Hmmm, some boffins from South Korea managed to use human skin as a medium to transmit data, with a recent experiment capable of touching the 10Mbps mark – putting many Internet connections around the world to shame. This experiment relied on small, flexible electrodes to achieve such a result, and could possibly be developed into a new generation of medical devices which is capable of monitoring blood sugar or electrical activity in the heart. These devices will reduce energy needs for a monitoring network by about 90% compared to wireless devices running on batteries. Shame on you, copper wires!
