A few days ago we highlighted the capabilities of a miniature action camera that could be installed on the back of an insect to make observations of the environment from a new perspective.
Under this same premise, but in a different context, a group of researchers under the leadership of the University of Adelaide and the University of Stuttgart turned to 3D microprinting in order to create the smallest and most flexible endoscopic camera in the world in order to use it. to make observations within the blood vessels.
In this way, they obtained a device similar to a camera with the capacity to be inserted into the blood vessels and generate high-quality 3D images, which allow scientists to acquire a better understanding of the causes associated with heart attacks and the development of diseases. in order to create more effective treatment and better prevention policies.
As noted in the study published in the journal Light: Science & Applications, the team of researchers and clinicians in charge managed to print a tiny lens the thickness of a human hair on the end of an optical fiber, which would be used to scan successfully. the blood vessels of mice
The optical design and simulation group at the University of Stuttgart was led by Dr. Simon Thiele who was also responsible for the creation of the small lens.
In reference to the achievement obtained, Dr. Thiele expressed Until now, we cannot make high-quality endoscopes that small  Using 3D micro printing, we are able to print complicated glasses that are too small to see with the naked eye. The entire endoscope, with a protective plastic housing, is less than half a millimeter in diameter
