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.
