New Chemical Iris Technology May Change the Way Smartphone Apertures Work

As smartphones have gotten smaller and smaller, the need for the cameras inside of them to shrink has become more pressing. One area where there's a lot of room for improvement is in the traditional mechanical aperture.

As we begin to hit the physical limit of the overlapping blades, researchers at the University of Kaiserslautern have designed an exciting new ‘micro iris’ that uses small chemical rings rather than a physical blades, dramatically shrinking the size of the aperture components in the camera.
