“…This approach addresses the issue faced by continuous thin films, which tend to crack under strain, leading to discontinuities and a significant reduction in conductivity. − Among the nanomaterials, Ag-based nanocomposites are considered one of the best candidates for strain sensors and interconnects owing to their high electrical conductivity, chemical stability, and cost-effectiveness. − In this research, for the context of developing sophisticated stretchable displays, Ag thin film has been selected as a fundamental layer, utilizing the sputtering processa commonly employed process in commercial display manufacturingfor its superior integration capability and reliability. However, as mentioned above, sputtered Ag thin films on stretchable elastomer substrates are fragile, even at low external tensile strain, leading to entire rupture or cracking due to their intrinsically poor ductility under tensile strain. − Hence, constructing a wrinkled structure by performing the Ag sputtering deposition onto a 10% prestretched polydimethylsiloxane (PDMS) substrate using a shadow mask was attempted as shown in Figure a. This helps dissipate the strain stress and reduces the occurrence of abrupt thin film fractures.…”
