A group of researchers from the Princeton University and the University of Washington has announced the development of a high-resolution full-color camera for the size of a grain of salt, a that “will be the next generation of metasurface technology.”The approach is not new, in fact the development of tiny cameras that they had the potential to detect problems in the human body and help scientists and medical professionals treat various diseases. The problem was that they had only been able to produce blurry and distorted images with limited fields of view.
To do this, the camera works thanks to something called a metasurface. This material is covered with 1.6 million cylindrical posts, each one of the “size of a human immunodeficiency virus (HIV) particle “. Each cylinder It works like an optical antenna and has a precise design
HabThe blades of a camera as small as half a millimeter wide that can produce photos like a camera with a lens very much larger in volume. A technological advance that, as we said, could be used to find medical problems or as a sensing device for extremely small robots.(For example, in endoscopy)
