| Outline of Final Research Achievements |
In recent years, flexible materials and devices have drawn much attention. However, deformation behavior of soft materials, which compose those devices, remains unexplored. Mechanical analysis of deformed soft materials is of great importance in the development of flexible devices. We introduce a surface labeled grating method that can be applied to various materials to investigate the surface deformation of flexible films. In this study, a polydimethylsiloxane (PDMS)-based film, which is flexible, colorless, and optically transparent, was employed to confirm availability of the surface labeled grating method to surface strain analysis of common films. Surface strain was controlled by materials design, and in a bilayer film with different hardnesses the surface strain was greatly reduced.
