Engineers at the University of Stuttgart in Germany have designed an “imaging system” so tiny that it can be sent straight into human tissue.
The system is based on a three-lens camera built using 3-D printing. The camera has a lens just 100 micrometers wide that can focus on images up to 3 millimeters away and relay them back through an optical fiber.
The Stuttgart team has published a report on their work in the journal Nature Photonics, and Phys.org has more info plus photos:
