Even this Micro Camera can be injected into human body

German Engineers created Micro camera which is not even size of small grain of salt which is going to be a revolution in future of science. This Micro camera which is made by 3D printing technology,scientists fits it onto an end of an optical fiber.This can be used for exploring inside the body as minimally intrusive endoscope which can bring into action in virtually invisible security monitor or mini robots. For designing and manufacturing it just took few hours and these tiny eye which provides a very high optical performances. The compound lens is 100 micrometer (0.1mm) wide. It can focus object at a distance of 3 mm as the optical fibre can relay upto length of 1.7 m. This imaging system perfectly fits into a standard syringe needle so that it can be easily injected into our body.
