Some natural creatures have interesting functions generated by micro structures on their body surface. Structural color is one of them. In this study, we have tried to mimic it and use as mechanical applications. In this report, a rubber sheet having blazed grating has been developed. The sheet was realized by vacuum injection method. Because of softness of rubber, the sheet can be stretched. Then following the deformation, structural color is changed. We have confirmed the relation between extending rate of the sheet and appeared color experimentally. Additionally the rubber sheet has been mounted on a soft bending actuator, and color change following actuator motion has been observed. It indicates that the sheet has potential as a strain sensor.
