The Human Arm: An Information Superhighway?

Scientists at Korea University in Seoul have demonstrated a prototype of a new biomonitoring system that transmits data through the body, replacing wires and minimizing the need for batteries.

The device was tested for skin safety after continuous wearing and the data was transmitted via low-frequency electromagnetic waves through the skin.
