Mechanical characteristics of stretchable electronics based on a mogul-patterned structure

Recent progress in unconventional forms of foldable and stretchable electronics has enabled development of novel electronics. Especially, stretchable electronics have attracted much interest for applications that require reliable operation under mechanical deformation. Stretchable electrodes can be bent, stretched and compressed while maintaining good performance and structural safety. To realize flexible electronics, stretchability of devices, which requires a deeper understanding of nanoscale materials and mechanics, is needed. In this study, the mechanical characteristics of electrodes based on a mogul-pattern, which retain their electrical conductivity under mechanical deformation, were evaluated. Nanostructured patterns and thin film material were considered for stretched and bent models. The von Mises stress and strain distribution were analyzed and depicted graphically.
