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 is 300 micrometres thick and in a test, using a metal electrode coated with a flexible silicon-rich polymer, the researchers transmitted data at a rate of 10 megabits per second through a person’s arm. The device was tested for skin safety after continuous wearing and the data was transmitted via low-frequency electromagnetic waves through the skin.
The technology may have implications for diagnostics, as it can be used to detect electric fluctuations as is currently done by ECG and EEG machines.
