    A curved CMOS sensor has a few advantages over a planar sensor. Because of the geometry, it can be paired with a flatter lens and a larger aperture, which lets in more light. Photodiodes at the periphery of a sensor array will be bent toward the center, which means light rays will hit them straight on instead of obliquely. What's more, the strain induced on a CMOS sensor by bending it alters the band gap of the silicon devices in the sensor region, lowering the noise created by "dark current" — the current that flows through a pixel even when it is receiving no external light.

    I for one am excited to see this voodoo magic in action. It's quite a brilliant idea to not only make a lens curved like the front of an eye, but make the sensor curved like the back of an eye. Our eyes, if anything are good at seeing things... so it makes sense.
