In recent years, mech. properties of flexible materials have attracted much attention for the development of stretchable electronic devices, flexible sensors and wearable biointegrated devices that would support the future ‘Internet of things’ (IoT) and ‘information technol.’ (IT). For designing advanced soft devices, there is a strong demand to quant. analyze the deformation behavior of soft materials. Recently, a surface labeled grating method has been developed as a new tool to quant. measure the bending behavior of flexible films. In this study, we investigated the effect of hardness of the film to be measured on the surface strain evaluated by this method.
