Bionic Bodies: Marrying electronics and biology promises new devices that could transform millions of lives [...]
Ultimately, scientists want to "grow" living tissue that will eliminate the need for a transplant. For that, "we want to design smart materials that can sense their environment and adapt," says Allan J. Russell, director of the University of Pittsburgh's McGowan Institute for Regenerative Medicine. Bionic devices already available are halfway to Russell's goal. The Dobelle Institute in Lisbon, Portugal, has developed a pair of glasses that combine a tiny video camera, a handheld computer, and a grid of electrodes embedded in the part of the brain that processes visual images.
