Scientists from Germany have made a camera sticking into the needle's poison
German researchers at the University of Stadgard have developed a small camera the size of a grain of salt, which can enter into the injection needle hole. Scientists used a three-dimensional laser printer to build the camera with three lenses. So that these lenses are installed on the tip of fiber optic thickness of a hair. The diameter of these lenses is 100 μm, or ten millimeters.
The lenses can capture clear images at a distance of 3.0 millimeters and can reach a distance of 1.7 meters through optical fiber.
Such a technology could be used to explore the human body from the inside with minimal impact. The camera would be suitable for entering the brain, for example, and although its manufacture would be medical, it could be used in future spy cameras.
