Materials and structural designs of stretchable conductors

摘要

Stretchable conductors are essential building blocks for stretchable electronic devices used in next-generation wearables and soft robotics. Over 10 years of research in stretchable electronics has produced stretchable sensors, circuits, displays, and energy harvesters, mostly enabled by unique stretchable conductors. This review covers recent advances in stretchable conductors, which have been achieved by engineering their structures, materials, or both. Advantages, mechanisms, and limitations of the different classes of stretchable conductors are discussed to provide insight into which class of stretchable conductor is suitable for fabrication of various stretchable electronic devices. The significantly improved electronic performance and wide variety of stretchable conductors are creating a new paradigm in stretchable electronics.
