Stretchable form of single crystal silicon for high performance electronics on rubber substrates

摘要

The present invention provides stretchable, and optionally printable, semiconductors and electronic circuits capable of providing good performance when stretched, compressed, flexed or otherwise deformed. Stretchable semiconductors and electronic circuits of the present invention preferred for some applications are flexible, in addition to being stretchable, and thus are capable of significant elongation, flexing, bending or other deformation along one or more axes. Further, stretchable semiconductors and electronic circuits of the present invention may be adapted to a wide range of device configurations to provide fully flexible electronic and optoelectronic devices.

主权项

1. A two-dimensionally stretchable electronic device comprising:
a flexible substrate having a supporting surface; and a semiconductor structure supported by said supporting surface and having a spatially-varying contour profile that varies in at least two lateral spatial dimensions relative to the supporting surface, wherein the semiconductor structure is discontinuously bonded to said supporting surface; and wherein the contour profile varying in at least two spatial dimensions accommodates stretching, compressing, and/or flexing in more than one direction without device failure.
