Description
Su-Bon Kim and co-authors designed stretchable display panels that grow evenly in all directions, so pictures stay true when pulled. Ordinary stretchable screens distort because the base shrinks sideways when stretched lengthwise. Frames with a negative Poisson ratio, which widen as they lengthen, fix that on paper, yet their hole-filled build cannot carry a display alone.
The team bonded such frames to smooth stretchy sheets at carefully chosen points only, so the frame could still rotate while the sheet stayed calm. A new yardstick, the isotropic expansion factor, measured distortion across scales from local patches to the whole panel. Panels built this way expanded evenly without visible image warp and kept working through repeated stretching. The work speaks to wearables and soft devices that must flex without bending the picture out of shape.
