~ Foldable and stretchable, silicon circuits conform to many shapes

»Foldable and stretchable, silicon circuits conform to many shapes
ξ scientists developed a new form of stretchable silicon integrated circuit
ξ it can wrap around complex shapes such as spheres, body parts and aircraft wings !
ξ it can operate during stretching, compressing, folding and other types of extreme mechanical deformations !
ξ and without a reduction in electrical performance
ξ to create their fully stretchable integrated circuits,
ξ the researchers begin by applying a sacrificial layer of polymer to a rigid carrier substrate
ξ on top of the sacrificial layer they deposit a very thin plastic coating, which will support the integrated circuit
ξ the circuit components are then crafted using conventional techniques for planar device fabrication,
ξ along with printing methods for integrating aligned arrays of nanoribbons of single-crystal silicon as the semiconductor
ξ the combined thickness of the circuit elements and the plastic coating is about 50 times smaller than the diameter of a human hair.
ξ the work was funded by the National Science Foundation and the U.S. Department of Energy

ξ John Rogers is a Founder Professor of Materials Science and Engineering at the University of Illinois.
ξ “We’re opening an engineering design space for electronics and optoelectronics
ξ that goes well beyond what planar configurations on semiconductor wafers can offer,” /John Rogers/

ξ made possible by a generous gift from U of I alumnus and founder of Beckman Instruments, Inc., Arnold O. Beckman, and his wife Mabel M. Beckman,
ξ with a supplement from the State of Illinois.
