Flexible and Stretchable Oxide Electronics

Electronic applications that offer flexibility and stretchability have attracted increasing interest over the past few years because of their potential applications in, for example, electronic skin and bio-inspired devices, where electronics based on current wafer-based technology are not suitable. Metal-oxide-based binary and ternary systems offer the opportunity for large-area uniform synthesis of materials with excellent electrical performance. This review mainly focuses on basic flexibility and stretchability concepts that can be integrated and applied to all inorganic-material-based electronic devices. Possible fabrication methods are also discussed, and oxide-based electronic applications summarized in this context. Finally, the review is concluded with a discussion of future prospects of oxides in flexible and stretchable devices.
