Abstract
Disclosed is a stretchable, three-dimensional tubular structure formed due to processing-induced wrinkles to result in a platform for stretchable interactive electronics. The three-dimensional tubular structure is fabricated simply by releasing a pre-stretched two-dimensional film-substrate precursor, and the resulting wrinkled surface shows a strong directional dependence that drives the tube formation.
