Gallery: Scientists develop eye-shaped camera

Researchers have developed a camera that's about the same size and shape of a human eye, and see it developing into sharper pictures and even a bionic eye.

Researchers at the University of Illinois and Northwestern University have developed a camera with a layout similar in size and shape of the human eye. The eye camera is based on "single-crystalline silicon detectors and electronics, configured in a stretchable, interconnected mesh," according to the University of Illinois.

The curved technology will put an entire image in focus in contrast to today's cameras which take images that are sharper in the center than near the edges, according to researchers. Plus, the technology could be a big step toward the development of a bionic eye similar to the one worn by the "Terminator."

The National Science Foundation, one of the sponsors of the research describes this image: "Captured during the electronic eye fabrication process, shows a silicon focal plane array (dark brown) and electronics on a hemispherical transfer element (translucent)."

This mesh-like material is made up of tiny squares that hold the photodetectors and electronic components. This allows the structure to curve like the eye.

“Conformally wrapping surfaces with stretchable sheets of optoelectronics provides a practical route for integrating well-developed planar device technologies onto complex curvilinear objects,” said John Rogers, the Flory-Founder Chair Professor of Materials Science and Engineering at Illinois. Rogers worked on the project with Yonggang Huang of Northwestern University in Evanston, Illinois.
