Curved imagers that can adjust their shape could have many valuable applications, for instance, aiding the development of more advanced medical imaging tools and cameras. Most existing flexible curvy imagers, however, are either not compatible with tunable focal surfaces or can only capture images with low resolutions and pixel fill factors.

Researchers at University of Houston and University of Colorado-Boulder have recently designed and created a curvy and shape-adaptive imager with high pixel fill factors. The new imager, presented in a paper published in Nature Electronics, was fabricated by transferring an array of ultrathin silicon optoelectronic pixels with a kirigami design onto curvy surfaces, using a technique known as conformal additive stamp printing.
