Intrinsically stretchable conductors and interconnects for electronic applications

Recently, stretchable electronics with excellent mechanical stretchability and electrical properties have potential important applications in various electronic devices. Intrinsically stretchable conductors and interconnects are the indispensable components of soft electronics, including mechanical sensors, wearable devices, energy harvesters and biomedical devices. In this review, we summarize the recent progress in intrinsically stretchable conductors and interconnects as well as their applications in stretchable electronics. The focus will be on a variety of intrinsically stretchable conductors and interconnects based on metallic nanowires, liquid metals, carbon nanomaterials, conducting polymers and conductive composites. Moreover, directions for further research of intrinsically stretchable conductors and interconnects will also be discussed.
