摘要：

Various methods have been developed to fabricate highly stretchable electronics.Recent studies show that over 100% two dimensional stretchability can be achieved by mesh structure of brittle functioning devices interconnected with serpentine bridges.Kim et al show that pressing down an inflated elastomeric thin film during transfer printing introduces two di-mensional prestrain,and therefore further improves the system stretchability.This paper gives a theoretical study of this process,through both analytical and numerical approaches.Simple analytical solutions are obtained for meridional and circumferential strains in the thin film,as well as the maximum strain in device islands,which all agree reasonably well with finite element analysis.
