Body as Personal Area Network
Chips that really get under your skin
"Researchers at the Korea Advanced Institute of Science and Technology (KAIST) presented a chip that is implanted in a user’s forearm to function as an audio signal transmission wire that links to an iPod. Many of the presentations featured devices that conserved power, though this chip goes a step further, harnessing the human body’s natural conductive properties to create personal-area networks. It is not practical to wire together the numerous devices that people carry with them, and Bluetooth connections fall prey to interference, leading scientists to explore the application of the human body as a networking cable. The Korean scientists augmented an iPod nano with their wideband signaling chip. When a user kept his finger pressed to the device, it transmitted data at 2 Mbps, at a consumption rate lower than 10 microwatts. Researchers from the University of Utah also presented a chip that scans brainwave activity by wirelessly streaming data through monitors in the hopes of creating prosthetics that quadriplegics could operate with their brain waves, though both projects are still in the preliminary research stages. (…) These chips are not something that will be included in one of Apple Computer CEO Steve Jobs’ Macworld keynotes anytime soon." ACM Technology News.
