The relative resistance changes of the PEDOT:PSS/PEG hybrid films on PDMS. Moisture stability tests: (a) submerged in DI water for 10 days; and (b) ultrasonicated in DI water for 3 h. The fracture and degradation of the PEDOT:PSS that lead to the resistance increase were investigated by varying the PEG layer thickness, assuming that a thicker structure would lead to a larger surface strain and more interfacial cracks. Bending tests: (c) bending from flat to a 5 mm bending radius; and (d) repeated bending from flat to a 10-mm bending radius for 1000 cycles. Tensile tests: (e) external tensile strain from 0 to 100%; and (f) repeated stretching with 10% strain and 20% strain, respectively.
