Recently, research has turned to using the human body as a medium for data transfer, also known as a personal area network. At the International Solid State Circuits Conference in San Francisco, researchers from the Korea Advanced Institute of Science and Technology modified an iPod nano to use a human finger to transfer audio signals to the earphones. So long as the finger remains in contact with the conductor, the audio signals are transmitted from the nano, through the person, and finally to the earphones. Also featured at the conference were chips designed by the University of Utah that transmit data wireless from a person's brain. These chips, designed to monitor the brain waves of patients, used to output data via a wired connection. That's right: cables went from chips in a person's brain to an external monitoring device, which is probably not the most comfortable situation. Innovations like these probably won't make their way to consumer devices any time soon, but what the future hold's is anyone's guess.
