University of Illinois Professor John Rogers, left, and postdoctoral student Heung Cho Ko are seen through an artificial retina in an electronic testing lab at the Materials Research building in Urbana. Their latest device took more than two years to develop.
Silicon chips are hard, flat and brittle. Human flesh is soft, curved and yielding. They would not seem a good match for each other.
But John Rogers, a University of Illinois materials science professor, has found a way to make silicon bendable and stretchable, so that it can wrap around heart muscle to stimulate it more effectively than a pacemaker, or stretch around brain tissue, or most recently, create an artificial retina.
