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