Instead of using a flat microchip as the light sensor for their new camera, the engineers developed a sensor that is a flexible mesh of wire-connected pixels. The mesh is made from many of the same materials as a standard digital-camera sensor, but has the unique ability to conform to convoluted, irregular surfaces.
This picture was captured during the electronic eye fabrication process, and shows a silicon focal plane array (dark brown) and electronics on a hemispherical transfer element (translucent).
