Studying the strain of materials on a small scale is very important for applications in strain sensors. Previous studies show that graphene is a promising candidate for strain sensors because of its extraordinary physical and electrical properties. However, these studies were limited to strain applied in a single direction. In this study, flexible strain sensors based on graphene were fabricated and evaluated for strain applied in two directions. For this, the CVD graphene was crumpled with the help of a pre-stretched silicone film. The preliminary results for applied strain in one direction by keeping a fixed strain in the other direction show a significant change in the resistance, up to 20 kΩ.
