a Critical strains for delamination in different combinations of rigid island/elastomer materials. b Scanning electron microscopy (SEM) images of PEA/PUA and PEA/PDMS substrates under 0% and 30% strain. c SEM images of PEA/PUA substrate under 90% tensile strain. The PEA island is delaminated from PUA with a web-like structure at the interface. d FEA simulation for strain distribution and volume average stress of the PEA rigid island. e Simulated strain at the center of the rigid island and the volume average stress under 30% of tensile strain with different PEA thickness. f Schematic cross-section of PEA/PUA substrate with EGaIn interconnects. g Bending simulating condition for PEA/PUA substrate with EGaIn interconnects. h Strain distributions in PEA/PUA and PI/PEA/PUA substrates.
