1. A stretchable semiconductor element comprising:
- a flexible substrate having a supporting surface; and
a semiconductor structure having an internal surface, wherein discrete points of said internal surface are bonded to said supporting surface of said flexible substrate and said discrete points of bonding are separated from each other by a buckled region of the semiconductor structure that is not directly bound to said flexible substrate, wherein said buckled region of the semiconductor structure is not in physical contact with the supporting surface of the flexible substrate.

Abstract
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.
