New Medical Camera the Size of a Grain of Salt

kkleiner writes "The German Fraunhofer Institute for Reliability and Microintegration recently reported the development of a camera with a lens attached that is 1 x 1 x 1.5 millimeters in size, which is roughly as big as a grain of salt. At about a cubic millimeter in size, this camera is right at the size limit that the human eye can see unaided. The camera not only produces decent images but is also very cheap to manufacture — so cheap, in fact, that it is considered disposable."
