Micro-camera can be injected with a syringe

Little wonder: A tiny camera could be fitted in a syringe, changing the field of medical imaging.

Using 3D printing, researchers from the University of Stuttgart built a three-lens camera, and fit it onto the end of an optical fibre the width of two hairs.

Such technology could be used as minimally-intrusive endoscopes for exploring inside the human body, the engineers reported in the journal Nature Photonics.
