South Korean scientists transmit broadband signals through a human arm

Posted in News by Conner Flynn on March 16th, 2010

Need a hand with your data? How about an arm? Turns out that human skin is a very energy-efficient conduit for transmitting data. And why not? It can transmit electricity. In fact, a recent experiment achieved a rate of 10Mbps. In the experiment they used small, flexible electrodes.

The news might lead to new medical devices that can monitor blood sugar or electrical activity in the heart. Devices that could cut energy needs for a monitoring network by about 90 percent compared to wireless devices that run on batteries.

The scientists placed electrodes about 12 inches apart on a human arm, and found that the low-frequency electromagnetic waves travel easily through the skin without any outside interference.
