Insect eye-inspired camera captures wide field of view with no distortion
By mimicking the bulging, bowl-shaped eyes possessed by dragonflies, praying mantises, houseflies and other insects, a team of researchers that includes a University of Colorado Boulder engineer has built an experimental digital camera that can take exceptionally wide-angle photos without distorting the image.
“The most important and most revolutionizing part of this camera is to bend electronics onto a curved surface,” said Jianliang Xiao, assistant professor of mechanical engineering at CU-Boulder and co-lead author of the study. “Electronics are all made of silicon, mostly, and silicon is very brittle, so you can’t deform the silicon. Here, by using stretchable electronics we can deform the system; we can put it onto a curved surface.”
