We introduce an unprecedented auxetic structured stretchable film capable of achieving a negative Poisson’s ratio of -1. This is realized by embedding a rigid auxetic structured reinforcing glass-fabric inside surface-flattening soft elastomers. Using the developed auxetic film, we demonstrate an aspect ratio distortion-free stretchable micro-LED display capable of 25% stretching without performance degradation.
