Abstract
Stretchable displays are garnering attention due to their ability to undergo reversible shape deformation. However, due to Poisson's ratio, image distortion issues caused by undesired substrate deformations during stretching remain challenging. Here, we propose meta‐elastomers with biaxially zero Poisson's ratio for distortion‐free stretchable displays. To program the Poisson's ratio according to biaxial stretching, elastomeric mechanical metamaterial (MM) frames with a negative Poisson's ratio are integrated into an elastomer matrix. By leveraging competitive interactions between the elastomeric MM frame and elastomer matrix deformation, we have successfully implemented the biaxial near‐zero Poisson's ratio substrates.
