Abstract

Interface delamination in metal–rubber-type stretchable electronic systems leads to early failure. This paper reports an investigationof metal–rubber interfaces through in situ scanning electron microscopy imaging of the progressing delamination front of 90 Degreespeel tests of rubber on copper samples. The results show that the energy dissipated in the forming, elongation and rupture of~50 micrometer long fibrils constitutes the major part of the work of separation. The experiments are characterized and modeled usinga cohesive zone-enriched finite-element model.
