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.
Claims20
A stretchable three-dimensional tubular structure, comprising:
- a multilayer film comprising a first polymer layer or a first polymer composite layer bonded to a first elastomer layer, wherein the first polymer composite layer comprises a polymer and an inorganic material;
- the multilayer film is substantially to fully tubular in structure comprising an openable seam;
- the first elastomer layer forming an outer surface of the tubular structure;
- and
- the first polymer layer or first polymer composite layer forming an inner surface of the tubular structure, wherein the inner surface has a wrinkled morphology.
