Curvy adaptable imaging sensor improves image, retains more pixels

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. The curvy imager developed by the researchers is inspired by the shape of human eyeballs. Just like a human eyeball curvy cameras should be made of a curvy and shape adaptive imaging sensor array and a lens. "Our work paves way to achieve curvy, shape tunable adaptive/tunable imager with high pixel fill factor to guarantee imaging capture with high quality and low optical aberration," Yu said.
