(Bottom) Typical elastomer with Poisson's ratio of 0.5 (severe vertical contraction, left), and aligned fiber composite for controlling Poisson's ratio near 0 due to the high stiffness of fibers ...

Overcoming Poisson's ratio enables fully transparent, distortion-free, non-deformable display substrates. (Nanowerk News) Stretchable display materials, which are gaining traction in the ...
