報告摘要：
Intrinsically stretchable electronics entails the electrode, semiconductor, and dielectric materials all being deformable, and that a suitable deposition, patterning, and overlaying protocols are developed for the soft materials. I will present the development of a new transparent conductor with high surface conductivity and low surface roughness. The mechanical properties of the transparent electrode are determined by the polymer substrate employed, and demonstrated properties include flexibility, shape memory, self-healing, and rubbery deformation. The new electrode has been used to replace ITO/glass in fabricating organic light emitting diodes with significantly enhanced luminous efficiency. A series of highly stretchable electronic devices will also be presented.
