German engineers have created a camera no bigger than a grain of salt that could change the future of health imaging—and clandestine surveillance.

Using 3-D printing, researchers from the University of Stuttgart built a three-lens , 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.

It could also be deployed in virtually invisible security monitors, or mini-robots with “autonomous vision”.

3-D printing—also known as additive manufacturing—makes three-dimensional objects by depositing layer after layer of materials such as plastic, metal or ceramic.

Due to manufacturing limitations, lenses cannot currently be made small enough for key uses in the medical field, said the team, which believe its 3-D printing method may represent “a paradigm shift”.

It took only a few hours to design, manufacture and test the tiny eye, which yielded “high optical performances and tremendous compactness,” the researchers reported.

The compound lens is just 100 micrometres (0.1 millimetres or 0.004 inches) wide, and 120 micrometres with its casing.
