Chips that really get under your skin Researchers at the Korea Advanced Institute of Science and Technology (KAIST) weren’t concerned with such weighty questions when they developed a chip that allows you to listen to an iPod using your forearm as the transmission wire for the audio signals. The chip was detailed in one of several presentations during a session called "Silicon in Biology" at the International Solid State Circuits Conference (ISSCC) here Thursday.
Low power consumption was a common design thread throughout the several different chips presented by university researchers. The need to reduce power consumption of chips has become a mantra for the PC and server processor industry, but low power consumption takes on a new meaning when referring to chips that will be used inside the human body or on skin.
KAIST has built a prototype chip it thinks solves some of the problems encountered in setting up personal-area networks that take advantage of the body’s ability to conduct electricity. Computer scientists have long envisioned connecting the numerous personal electronic devices the average technology fan carries around each day, but wiring those devices together is impractical, and Bluetooth connections are prone to interference, said Seong-Jun Song, a professor at KAIST.
